Bunton Instrument Co., Inc. has a long history of developing and building special accessories for use with microscopes. Having skilled machinists and a complete machine shop, we have crated many special items over the years. These include low magnification darkfield illuminators after Hinsch-Goldman and Mears. Lamp adapters to convert old Leitz microscopes to accept modern halogen lighting. Micromanipulator support bases and hydraulic microinjectors (see below) that were instrumental in the creation of transgenic mice and, yes, for human IVF methods.
We built the first Ploem illuminator in America back in the 1960's .... before E. Leitz offered it for sale on the Ortholux!
We stock just about every bulb made for Leitz and Wild microscopes. We also have a full line of replacement bulbs for most modern student, laboratory and research microscopes, as well as reflector bulbs for fiber optic illuminators. We can honor any University or government purchase order (minimum of $100.00) and are happy to quote quantity discounts for six (6) or more bulbs/three (3) or more mercury/xenon arc lamps. E-mail firstname.lastname@example.org with your microscope make/model plus lamp voltage and wattage requirements. Look for the ANSI three letter code on your reflector bulb for fiber optic illuminators(i.e., "DDL", "EKE") and we can quote you as a catalog number and price.
We have a limited stock of new and used RMS 160/45 objectives from Russia, China and Germany. .... Bunton can usually source from our own stock or our many other USA contacts, the correct optics for your older finite tube length instrument. We can review objectives and oculars found on ebay and tell you if they are the correct items. You can then order on your own from ebay once we give you the thumbs-up. E-mail your specific requirements and questions. A photo of your microscope is always helpful for I.D.
assorted items for optical microscopes:
LOMO optics for DIN (160mm or 170mm) transmitted light or incident light Fluorescence microscope. These 45mm parfocal optics are new and subject to prior sale.
Left to right in photo .... 50x OIL/IRIS, 100x OIL/IRIS, PLAN 2.5x and 40x WATER IMMERSION.
The immersion optics are perfect for incident light fluorescence or transmitted light darkfield microscopy using an oil darkfield condensor. The water lens should be used with a coverslip and is not intended for intravital work. The perfect mid-range immersion lens for routine fluorescence work.
This interesting item is designed to replace the glass plate on a transillumination base. It immediately converts the brightfield illumination to a darkfield illumination scheme. The highly polished conical mirror and darkfield "stop" will divert and block out direct rays and bring illumination rays at very oblique angles (back lighting). A perfect retrofit for your existing microscope for GEMSTONES, INSECTS, AQUATICS, BOTANICALS and many transparent/semi-transparent objects that will benefit from transmitted light darkfield. This is not to be confused with incident light darkfield as created for fiber optic ringlights. IRIS control lever in photo on LEFT .... for contrast control of the darkfield.
Combined transmission darkfield with incident light (LED, fiber optic or electronic flash). Use with colored filters or gels for Rheinberg-like illumination.
CAMERA LUCIDA (Drawing Attachment) .... for MOTIC K-Series stereo microscopes as well as older WILD stereo microscopes (M3, M5, M7/7S, M8 et al). Illustrators have been using "camera lucida" on microscopes for well over 100 years. Before film, this is how images were documented for text books and research. The drawing attachment is positioned LEFT or RIGHT and you will see your drawing superimposed on the optical image in the oculars. We also can offer Leitz compound microscopes with the Leitz DRAWING DEVICE for high magnification illustration. This is one accessory item that the Chinese makes have not created....."if you can see it, you can draw it".
VIDEO/PHOTOTUBE .... for MOTIC stereo microscopes as well as older M3, M5, M7, M8 models. Photo tubes include dual iris for improved contrast and depth of focus control. Shown with a small format camera but easily adapted for DSLR or MILC....optics selected are based on the camera sensor diagonal dimension to avoid vignetting. One viewing ocular port is "blank" when in the photo/video mode to your camera.
MOTIC NOW OFFERS A FULL SET OF PLANO APOCHROMATIC OBJECTIVES WITH HIGH NUMERICAL APERTURES FOR BRIGHTFIELD STUDIES. NOTE THE 40X/0.95 LENS (LEFT). THIS IS A GOOD EXAMPLE OF A LENS WITHOUT COVERGLASS CORRECTION FEATURE. SUCH LENSES ARE ALWAYS CORRECTED FOR USE WITH A #1.5 COVERGLASS (0.17MM THIN). USE OF A MOTIC OR OLYMPUS MICROSCOPE WITH INFINITY CORRECTION AND THE INFINITY PHOTO OPTICAL "INFOCUS" WILL MAKE THESE OBJECTIVES MORE USEFUL FOR Z-STACKING AND WSI DUTIES. THESE EXCELLENT LENSES ARE CORRECTED FOR CHROMATIC ABERRATIONS AND PERFECTLY FLAT FIELD OF VIEW FOR OPTIMAL PHOTOMICROGRAPHY IMAGING.
We have seen other versions of this item that do the same thing .... our innovation is to make the assembly DIY and include www.suguru.com moldable glue as well as small magnets and a stainless steel disc for quick interchange of black/white background plates and give the user the ability to move the sample for composition of photos or routine viewing. Our unit sells for $49.95 .... microscope makers and certain catalog houses charge hundreds! See RetroCUP on our YouTube channel. BART SIMPSON SAMPLE NOT INCLUDED!
This USA-made item works with the 4, 4S, 5, 5S, 5SE, 6, 6S, 7, 8 and X (10). NO CASE for PLUS SIZES. Bunton supplies a special 10x eyepiece (23.2mm or 30mm) so you can use the Arcturus on a microscope viewing port. Many existing oculars will have adjustment rings or dimensions that will not permit use of the clamp mechanism. A set of blue rings is included with each Arcturus for snug connection with the clamp ring. If you have a microscope with a dedicated camera port (trinocular), we also provide a version of Arcturus that will include a C-mount ocular holder and the 23.2mm 10x eyepiece for connecting your iPhone to an existing c-mount (1X) camera coupler. This is ideal for photomicroscopy since the camera is now out of the way of binocular viewing oculars and may be left on the microscope for quick insertion of your iPhone when needed. Put older model iPhones to use (RRR) as dedicated microscope cameras.....not collecting dust in your junk drawer. Made in the USA.
The digital camera image may be the ideal way to view your sample for analysis, processing and photomicroscopy. ULTIMA is a product that replaces a trinocular body tube, eyepieces and expensive camera couplers. It may be used with small format (c-mount) cameras or large format sensor cameras up to full-frame 35 (43mm diagonal). They are microscope make-specific and only for the current generations of infinity corrected upright microscopes. Optics inside of ULTIMA are specific for objectives made by Nikon, Olympus, Motic, Zeiss and Leica. A unique feature exists for parfocalizing two objectives .... 10x and 40x for example. The ULTIMA is ideal for dedicated photo systems or any microscope workstation that involves 100% display monitor interaction .... such as MICROVISIONEER image stitching package offered by Bunton (manualWSI).
Similar look to the ULTIMA, the INFOCUS is much more. The patented optical design permits "dynamic focusing" of your sample (transmitted light biological slides) at high magnification. The idea is to correct for spherical aberrations caused by samples with incorrect coverglass thickness. Most transmitted light objectives will be corrected for a coverslip that is 0.17mm thick (#1.5). If you use a coverslip that is thinner or thicker you will end up with a "soft", low contrast image. The old solution is to have mid-range dry objectives with a coverglass correction collar. Inverted microscopes may have a correction collar for adjusting the thickness of the dish or chamber in which the cells are growing. Correction collars are rarely used properly. ULTIMA and INFOCUS are for upright style microscopes. You must also consider the thickness of the mounting media between the sample and the coverslip .... this is usually unknown. It becomes very subjective in that you adjust the collar on the objective until the detail looks best. The INFOCUS includes its own large knurled ring to internally adjust for the optimum optical setting when doing critical photomicroscopy, realtime digital viewing or digital cine. INFOCUS then, does not require objectives with correction collars. You could use them and just leave them at one setting (0.17). Use INFOCUS to fine-tune the detail until it looks best to your eye. Nothing like this on the market .... dynamic focusing. For use with any digital camera (up to full frame 35 size)you may select. No eyepieces needed.
The two images below were captured by Dr. Brian Matsumoto. He used an Olympus infinity corrected plan apo 40x (dry) with n.a.=0.85 with coverglass correction collar. Sample is a trichrome-stained fibrous cartilage (left 1/3). Left photo with correction collar set incorrectly while the right photo shows the same sample with the correction collar in the correct position. High dry objectives without a correction collar (i.e., fixed at 0.17mm coverglass thickness) will not provide one with all-around good results.....INFOCUS solves this problem!
BOTH ULTIMA AND INFOCUS ARE EXCELLENT OPTIONS FOR USE WITH MICROVISIONEER WSI WORKSTATIONS.
The optical "core" of old 35mm film attachments are ideal for use with digital cameras of all types. Bunton has been "adapting" old systems like Micro-IBSO, KAVAR, ORTHOMAT-W/II and MPS for years. We simply get rid of old 35mm film backs and replace them with M42 tubes of the right size so that c-mounts and R-mounts (large format cameras) may be added as needed for your digital camera of choice. The photo (red component) is our RPM adapter for your DSLR camera mounted on the classic Leitz Ortholux One microscope .... again RRR!! If you have an old Leitz, Leica or Wild film camera that is collecting dust let us know. We can help you convert to DIGITAL!
We also offer a full line of new DSLR camera couplers....another option is to replace old binocular viewing tubes completely with ULTIMA and INFOCUS in the previous sections. These modules may be used with DSLR or MILC sensors up to "full frame 35" (24mm x 36mm).
