We specialize in the E. Leitz Wetzlar German-made legacy microscopes from about 1960 to 2000. These precision compound microscopes are completely cleaned and serviced with a ONE YEAR BUNTON WARRANTY PERIOD. Instruments are offered for both biological and industrial applications. Most have phototubes for connection of a modern digital camera. See our section on REPAIR AND SERVICE regarding our expertise in those areas. Most sellers of used microscopes are not able to pack them properly for shipment....much less make them usable by the microscopist. Beware of used microscopes being sold on-line "as is" or without a warranty. Many are missing key components or equipped with objectives/oculars made by other microscope brands. We stand behind our RRR microscopes and make sure the new owner is totally satisfied with their purchase. BUNTON SELLS SOLUTIONS....our customers will quickly differentiate us from our competitors. We support you for years to come and we are always available for quick information or guidance on proper use of your microscope and accessory equipment. Expert service people are available upon request. Just ask.

The "Laborlux 160" series was introduced by Leitz as early as 1980 as a student model (Laborlux 11). These were the so-called 160 models that transitioned E. Leitz to the DIN standard (160mm tube length) for transmitted light. Prior to this model, E. Leitz corrected all of their transmitted light optics to their "own" 170mm tube length correction. Soon the model Laborlux 12 came to the market and this was followed by the D versions (coaxial coarse and fine focusing). The series ended by 1990 as the Laborlux-S model that you see in the LEFT PHOTO. We have a good selection of all models including Laborlux 11 student binocular models, Laborlux 12/D/S set up for fluorescence studies (PHOTO LEFT REAR). Alternative accessories are available for DRAWING attachments, MODULATION CONTRAST, PHASE CONTRAST and DIGITAL PHOTOMICROSCOPY.
All Leitz finite tube length microscopes were replaced in the early 1990's by the INFINITY TUBE LENGTH "DM (das mikroskop)" series. The Laborlux products were joined by other models....Dialux 20/EB/22, Diaplan and Aristoplan.

This microscope was so far ahead of the competition that it immediately became the instrument of choice in many tissue culture labs. The unique modular design with modern halogen lighting and easy-to-use phase contrast set up made the Diavert a benchmark for all others to follow. We normally always will have Diaverts set up for biological phase contrast methods. The perfect workhorse in a tissue culture lab. Prices start around $1650.00 with complete phase kit...optional photo tube.

Rare Epivert and Metallovert inverted metallographic microscopes available for inspection of polished opaque samples.
Launched in the 1930's as the world's first real modular research microscope stand. Primarily used for biological research, Ortholux was also used in pathology, geology, metallurgy, and materials science. It is an upright microscope and always comes with a phototube. Lighting is available as halogen, fiber optic or LED with modern configurations. Most of our Ortholux I models are for biology. It is a fantastic instrument for hobbyists who want a model to expand. Heine or Zernike phase kits. Ultropak for incident light darkfield studies of opaque sample with irregular surfaces. A Leitz exclusive!
Photo LEFT shows a fine Ortholux ONE model with modern finite tube length objectives. Yes, you can use "160" tube length corrected objectives on the "170 (mm)" Ortholux ONE....as long as they are higher than 10x. Any objective 10x and LOWER must be "170" tube length and made by Leitz for all objectives to be within parfocality specifications. Hope this ends some of the confusion of many folks giving incorrect info on various blogs etc.
We have adapters for modern LED lighting on the Ortholux ONE....we also offer 3D printed retrofit FILTER HOLDERS for the condensers #600 and #400. These permit the use of polarizers and first order red compensators. We also offer our own push-in PHASE/DARKFIELD module for use on the brightfield condenser series #600 (SHOWN LEFT). Insert this module one way to use it with PHACO 25 or 40 Leitz phase contrast objectives or insert it from the other end to get fantastic LOW MAGNIFICATION DARKFIELD using objectives down to 2.5X.
Shown (LEFT) with the FSA trinocular tube that keeps the camera sensor parfocal with the ocular focus. Add DSLR/MILC adapters...or even our own RRR optical core to allow VARIABLE MAGNIFICATION to the camera sensor...2x, 2.5, 3.2X allowing continuous field of view for your camera. Nothing like this on the market. Details upon request.

Ortholux II came out about ten years after the Orthoplan. It is totally modular but without the large field of view of the Orthoplan. It is a "170mm" optic instrument and a real step up from the Dialux noted above....note how the objective nosepiece turns "in" rather than "out" as on the Dialux model. This feature permits easier exchange of slides....and the nosepiece is quickly changed (as on Orthoplan) in a horizontal dovetail....quickly add a Ploem illuminator, Ultropak or seperate nosepiece with phase contrast components. They all come with trinocular FSA phototubes. Halogen 50W or LED options. Shown with DRAWING DEVICE...CAMERA LUCIDA attachment for left or right hand operation.
This is the upright "brother" for the Diavert inverted...everything is interchangeable.

Orthoplan II was the "160mm" replacement for the aging Orthoplan I. It was made as an early offering only for the US market since Orthoplan I had ended production and Aristoplan was not quite ready for world-wide launch. Orthoplan and Aristoplan have the option of an integrated Ploem illuminator for epifluorescence. Aristoplan then replaced Orthoplan II. Not many differences other than the nameplate. Note the ergonomic hand rests in the photo of Aristoplan. A Leitz unique feature on these models was the in-base controls for aperture and field diaphragm....i.e., the aperture diaphragm was not in the condenser! Rather, it was in the base and easily set up for Kohler with your left hand. The 12V power supply was built into the microscope base and 100W halogen was the basic lighting component. Several are offered with the ergonomic binocular viewing tube (tilting for operator ergonomics). The last of the Leitz finite tube length microscopes prior to launch of DM Series around 1991 (infinity corrected tube length). A pathologist's dream-scope ready for use with the Microvisioneer WSI stitching software (manualWSI).
Labovert replaced the Diavert model. Primarily used for cell culture, live cell micromanipulation/microinjection, the Labovert eventually came out with a "FS" (fixed stage) model that was more suitable for micromanipulation of cells in dishes....the objective nosepiece moved in the z-axis and the stage and sample remained in a fixed position. We have models with phase contrast, DIC or Ploem epifluorescence. Note the ergonomic position of the body tube.....easy on the neck. Most of our offerings of Labovert will include the "ergotube" invented by Leitz. This tube tilts the oculars 0-40 degrees and creates and erect image for comfortable viewing angles of both short and tall humans. Ideal for micromanipulation and routine cell culture photomicroscopy.

The FLUOVERT inverted research model shown in the second photo was the instrument of choice for those doing live cell studies involving fluorochromes. The typical lamp was HBO 100W mercury arc lamps but we can also offer this model with new LED illumination (below LEFT photo). This new LED illuminator has three spikes for blue, green and red emissions (INTRO PRICE UNDER $3000.00 WITH ADAPTER). FLUOVERT has a DUAL FILTER CUBE CHANGER built-in to the integrated Ploem illuminator. CHROMA in Vermont is our supplier for new filter cubes for just about any modern fluorescence study....just tell us your fluorochrome need and we can quote accordingly. CHROMA is a USA employee-owned corporation. We always have useable filter cubes (Leitz and Chroma) in very good condition. Labovert and Fluovert are both offered with mechanical stages. Photo: mouse egg undergoing transgenic microinjection...holding pipette left and injection needle on the right. Optics: differential interference contrast (DIC). PRICES START AROUND $3,000.00 with phototube and 100W halogen lamp.
BUNTON'S OWN RetroH2O open dish chamber with interchangeable 25mm coverglass for optimal resolution when using an inverted microscope. Microinjection or enclose the bottom coverglass with a second coverglass on top with a nice space in between for the sample....a reasonably-priced culture chamber that can be heated with a warm stage plate or external air curtain incubator. Shown (far right hand photo) mounted on a Labovert with interference contrast....yes, a glass coverglass will give you a far better image than a plastic dish with 1mm thick plastic. Nomarski works on polarized light and plastic dishes are not useable with these optical kits.
ALSO AVAILABLE FOR DIAVERT WITH NEO MAGNETS FOR USING RetroH2O without a mechanical stage....here we use a steel stage insert and you move the chamber as you would with an inexpensive "gliding stage". A Bunton creation that is now available for under $80.00!
The first image (BELOW) is a set of Leitz Ortholux ONE microscopes equipped with one of the world's first 35mm camera attachments for photomicroscopy. Makes sense....Leitz invented 35mm photography with the LEICA (LEItz CAmera) nearly 100 years ago! Just before WWII the Ortholux was introduced as the world's first modular resaerch microscope. It remained the benchmark research microscope for more than 25 years. Also notice the shot (PHOTO #3 BELOW) of the Leitz Micro-IBSO 35mm photomicrographic attachment with oculars. Bunton now adapts old MicroIBSOs, KAVARs (old code letter model that replaced MicroIBSO) with a M42 male ring so any modern DSLR/MILC can be used on these classic scopes with appropriate T-mount adapter for your make/model camera. RRR. We also adapt old MPS (WILD-Switzerland) as well as the famous Leitz Orthomat optical core for use with DSLR/MILC cameras. You can use full frame sensor cameras with these attachments since they were designed for 35mm film to start with.....24x36mm format. Most cheap DSLR microscope couplers not only have poor optical performance but they are only for the smaller APS-C CMOS sensor size (or smaller). Now we can even use iPhone adapters for photomicroscopy with 50-year old microscopes!

We also show an old "internal workings" line drawing of the 1965 era Leitz research model "ORTHOPLAN" (CENTER IMAGE) What a great design! This was the Leitz flagship research model for about 20 years. The main feature was widefield sample field of view with oversized prisms in the body tube and new plano (flatfield) objectives mounted on a 1x nosepiece (Ortholux 1 was 1.25x). Orthoplan I was offered for biological work as well as versions for polarized light, metallurgy and semiconductor quality control (wafers). Ocular field index was up to 28mm with Orthoplan I...more than 2x the field of view of Ortholux I.....loved by pathologists. This is the widest field of view a human can "handle" without moving your head or trying to get your eyes to focus at the extreme edge of the ocular field. Today, modern NOZL microscopes have these same limitations and 24mm seems to be the maximum field index when using 10x oculars on the research models.
Bunton Instrument is big on RRR. The Leitz microscope was one of the first commercial microscope makers to offer a 35mm camera attachment for their optical microscopes. The LEICA (LEItz CAmera) 35mm format camera was invented by Mr. Barnack of Leitz back in the early 1920's. The MICRO-IBSO (above) was the first add-on attachment that was dedicated to 35mm film. We round up old IBSOs, MPS (Wild Switzerland), Orthomat W and Vario Orthomat film cameras and do a bit of modification so that a modern DSLR or MILC (mirrorless interchangeable lens camera) can be now used with the proper optics for up to full frame 35mm sensor diagonals (43mm). No vignetting. We may have the only zoom option for a digital camera with large format sensor on the market. Typically we use a 10x photo eyepiece plus the Leitz/Leica 0.32X intermediate optical component. The original shutter in these attachments is either disabled or removed all together.
The back-end fixture is then installed....a male 42mm threaded ring that will then accept any T-mount adapter of your choice. These camera attachments are only available on our complete microscope offerings since they are getting scarce and hard-to-find these days.

LEITZ MICROSCOPES FOR MATERIALS SCIENCE....you are most likely aware of the "chip" shortage around the world. A major cause of delay in automobile production not to mention so many other electronic devices ranging from cell phones to dishwashers. The photo at your left is the LEITZ ERGOLUX microscope that was designed to scan 100mm and 150mm wafers on fab lines. A motorized nosepiece and ergonomic viewing tube allowed a tech in their space suit to inspect a bit easier for longer periods. BUNTON offers SECOLUX, ERGOLUX, SM-LUX HL, METALLOPLAN and even EPIVERT (inverted bench metallograph) RRR instruments for the study of just about any opaque sample.....semiconductors/chips/wafers, polished metal samples, material failure analysis, MEMS devices, surface studies, ore samples etc.
Send us one of your samples for a FREE ANALYSIS AND IMAGING plus a report on the optical and illumination system that may best serve your needs. Note the MPS adapter (red) in the photo that allows attachment of your DSLR/MILC. Halogen 100W shown but we also offer high intensity LED options. Optics are usually brightfield for brightfield/darkfield type. Polarized light and reflected light DIC are available if needed.
Today we are seeing many of the entry level student and laboratory microscopes coming from China. We are also seeing the major microscope makers (NOZL) having their basic microscopes made in China and then sold under their own brand name. Many microscopes coming to the USA from China will have a USA private label brand name and one never really knows the corporate maker in China. Only a few Asian microscope makers will have an international brand name....such as Meiji (Japan) and Motic (China). Some microscopes being promoted in the USA may have origins in Italy or India. Local tech support, PM, and repair must be a key factor when choosing a new microscope. Many independent repair shops will not work on non-functional off-brand microscopes. Most firms selling these no-name microscopes on line do not provide knowledgeable tech support much less service after the sale. What good is a five year warranty if you have to return your microscope to a remote location and be without its use for long periods. One thing is for sure,...we will not be seeing any American-made optical microscopes in the near future! Bunton RRR LEITZ MICROSCOPES should be considered if you can't afford a new NOZL instrument.

RRR COMPARISON MICROSCOPY ...COMPARATIVE STAINS OR FORENSIC TRACE EVIDENCE (HAIR, FIBERS, SOILS)
We have always been on the lookout for the pioneer comparison bridge from Leitz....view the two images side-by-side (hemispheres) or superimposed (full field of view). Designed for the crime lab, this bridge simply connects two microscopes. We have comparison systems available based on the older black Laborlux and the later Dialux models. The photo shows the last of the Leitz finite tube length model Laborlux-S. Note the RetroDiode LED control unit. Lighting is very critical for such comparison systems. You must be sure the color temperature and illumination is perfect so that both images being compared have the same background and color balance. Bunton offers a single fiber optic lamp with bifurcated flexible light guide or two seperate LED lamps with variable intensity ...color temp is the same for both sides no matter which one you choose. We have the optics that are matched magnification and normally set these units up with a phototube so a digital camera may be attached for documentation or training. Complete systems for less money than the bridge alone when it was new!
