Shopping for and purchasing used microscopes is a roll of the dice these days. Seldom will one find a completely serviced or correctly outfitted used microscope on the usual websites. Most sellers of used microscopes do not have a clue about their function or condition. Let the buyer beware! None of these sellers offer a warranty. We have seen offers for used Leitz microscopes that are missing lamps, power supplies, objectives...even the body tube and oculars. Rarely would you find a used Leitz microscope (or any other make) that has had the focus block lubed and adjusted properly....Bunton offers only complete systems and our warranty and support after the sale is a rarely found when you deal with individuals or companies lacking the necessary expertise in these areas. I am fortunate to have two gentlemen (former employees) who now do independent microscope servicing, repair, PM and modifications. Visit our "Microscope Service" section on this website. These are two very rare individuals with the expertise, tools and know-how needed for the care and feeding of optical microscopes. Others on our team include fellows with 3D printing design and print skills, CNC and machine shop services for adapters and special microscope accessories. We have a local digital technology expert in areas related to code, stepper motor control and all things involving the personal computer. Local showrooms in Frederick and Mount Airy, Maryland.
Contact me with any questions.....we stand ready to help you select a fine Leitz instrument to meet your needs and price range.
We have a full range of new microscopes ...even a selection of USA-MADE microscopes from Infinity Photo Optical in Centennial, Colorado. Please take a look at our complete website.

Bunton Instrument has been a Motic dealer since they began operations in North America. We have seen this line evolve from stereo and student microscopes to advanced microscopes for biological research, industrial and materials science, live cell/tissue culture microscopy. The photo to the right is the newest routine inverted phase contrast microscope with integrated flatscreen and camera for small group discussions and photomicroscopy. Motic is now a leader in WSI (whole slide imaging) with their latest EasyScan instruments. Visit "Computer Controlled Microscopy" page.
THE MOTIC BA310 P0L ...This model is set up only for transmitted light investigations of mineral thin sections. The BA310 POL is the perfect geology student microscope and may be set up for digital photomicroscopy. Optional XY mechanical stage and compensators (mica, gypsum and quartz wedge).
NEW FROM MOTIC...PANTHERA "TEC" RESEARCH MODELS FOR MATERIALS SCIENCE AND POLARIZED LIGHT STUDIES. The "POL" model with LED incident light vertical illuminator may be combined with transmitted light for mineral thin sections.
MADE IN AMERICA.....LED REPLACEMENTS FOR MERCURY ARC LAMPS. PAYS FOR ITSELF IN YEAR ONE BY ELIMINATING THE NEED TO PURCHASE $200.00 HAZARDOUS BULBS. THE PHOTOS BELOW SHOW THE SINGLE UNITS THAT CAN BE OPTIMIZED FOR GFP/FITC (BLUE LIGHT) OR TEXAS RED/RHODAMINE (GREEN LIGHT). USE YOUR EXISTING PLOEM ILLUMINATOR AND DEDICATED FILTER CUBES. BRIGHTER THAN HBO 50W MERCURY WITH FULL FIELD, HOMOGENOUS ILLUMINATION BEAM. THE PHOTO TO THE RIGHT OF THE MICROSCOPE WITH LED SHOWS AN OPTIONAL DUAL PORT BEAMSPLITTER THAT PERMITS SIMULTANEOUS ATTACHMENT OF BOTH BLUE AND GREEN LIGHT LED EXCITATION. NO MORE EXPENSIVE ARC LAMPS....EVEN HAS THE ABILITY TO QUICKLY ADJUST INTENSITY TO AVOID FLUOROCHROME QUENCHING.
THE TWO PHOTOS YOU SEE HERE WILL ILLUSTRATE THE RANGE OF PERFORMANCE MADE POSSIBLE BY THE INFINITY PHOTO OPTICAL K2-DISTAMAX. THE SAMPLE IC IMAGE ILLUSTRATES THE NWE FRONT OPTIC WITH AN ADAPTER FOR USE WITH A MICROSCOPE OBJECTIVE.....THE SECOND IMAGE (by Hillar Ilves), "HALF MOON" WAS CAPTURED USING THE K2 WITH NWE FRONT LENS.....NOTHING ON THIS ROCK CAN MATCH THAT CAPABILITY!
INFINITY PHOTO OPTICAL IN COLORADO, IS ONE OF THE VERY FEW MICROSCOPE BUILDERS IN AMERICA. The unique design of most models make these instruments true microscopes for use with digital cameras at the back-end. We have re this line for many years and have found some very interesting applications along the way. The K2 (below)) shows a stereo 3D binocular tube connected to the back end. A beamsplitter option (right) would permit attachment of a full frame DSLR camera or digital cine camera for full motion imaging ...including high speed recording of very rapid events. The NWE lens for K2 will focus from 27" to infinity. A simple adapter is offered so one could even use optical microscope objective lenses on the K2. A very unique instrument from a very unique company.
The photomicrographs captured by Charles Krebs will illustrate the optical performance merits of the Infinity Photo Optical InfiniProbe TS-160. The photo of the TS-160 mounted on a stereo microscope support stand is ideal for high resolution photomicroscopy with a DSLR or MILC.....the TS-160 comes with both a macro(on stand)and micro(on main photo)interchangeable front lens. Note the twin flash head fixture for high intensity flash units. Wireless Nikon flash heads are in the photo of the TS-160 on microscope stand. TS-160 is perfect for manual Z-stacking using software from Zerene or Helicon. Another unit is called the KC-VIDEOMAX. The KC may also be used with full frame cameras but it is optimized for use with motorized sample stages for automatic z-stacking with products such as our Retro-ZED described above. You will not get such images using a camera on even the best stereo microscope (single photo channel). You will have the ability to capture photomacro or photomicro images with the same microscope...simply by changing optical components. Use with your DSLR and small format (HD) camera (for training and group discussions) at the same time. Create EDF (extended depth of focus) Z-stacks that would be difficult or impossible to achieve with even the best single channel macrozooms.....for a lot less money. All are made in the USA with a five year warranty. Thanks to Charles Krebs for his fantastic photomacrographs captured with TS-160....all z-stacked for EDF.
The LEITZ DIAVERT microscope (shown below) is available for biotech labs or citizen scientists who wish to have a very modular microscope for samples ranging from live aquatic organisms to cultured cells. BUNTON offers a ONE YEAR WARRANTY on all of our RRR microscopes. Qualified microscope techs are hard to find in the USA. We have listed two for your consideration here in Maryland. The two most common issues with an optical microscope are the focus block and light source. Unfortunately there are quite a few "spit-and-polish" microscope "repair" techs in the USA but rarely will you find the expertise needed to address serious lubrication or part failures that are hidden from external inspection. Having the correct tools for microscope service is important. Using factory specified DIN lubricants is a must. Some tools are hand-made for disassembly of some Leitz focus blocks. One needs to know the exact procedure for disassembly, lubrication (with correct lubes) and reassembly and adjustment. Further, once in useable condition, the microscope will require periodic maintenance (preventative) to continue useable service and provide the user with first-class images. Simple DIY optical cleaning (front lenses of objectives, clean eyepieces and condenser lens) should be taught every user of an optical microscope. Even the correct cleaning solutions and tools must be on-hand for all users to keep things clean and clear as they use the microscope on a daily basis.
Today's microscopes can be difficult to use if one is not familiar with "all the bells and whistles", knobs, and switches. Many high end microscopes are now being used by the second or third generation scientists and, without an owner's manual, one can be at a loss for good operation technique. The basic controls are on all microscopes no matter the make or model. It is import to fully understand these basic functions and how to set up your microscope for the best image. Fortunately there is quite a bit of useful information on the internet and most NOZL microscope owner's manual are available upon request or easily downloaded. Older model microscopes may require one to search for original documentation. We can help for most NOZL models...or, at least, point you to a good website source or local expert in your area who should have manuals. We can also offer on-site training in microscopy and digital photomicroscopy for your staff.....contact us and we can discuss this option for the Mid-Atlantic region.
There are very few formal classroom courses that teach microscopy methods. Learning the basics is as simple as reading the owner's manual and visiting some of the free microscope-makers' educational websites.
