Special Accessories for Optical Light Microscopy
Fiber Optics Accessories

BUNTON INSTRUMENT CO., INC. has a long history of developing and building special accessories for use with microscopes. We built the first Ploem illuminator in America back in the 1960’s….before E. Leitz offered it for sale on the Ortholux!

Here are some special items that may come in handy for your work and make things easier and more efficient. We accept credit cards and PayPal.

NEW FROM VOLPI SWITZERLAND….
LED MICROSCOPE LAMP

LED illumination is now offered for most routine compound and stereo microscopes. We offer LED replacements for the normal halogen bulbs in the Motic BA410 and AE2000 models … very efficient illumination with 50,000 hour plus lifetimes. Fluorescence, darkfield and polarized light microscopy will call for more intensity than a single LED can offer. The Volpi (USA/Switzerland) LED high intensity model “intraled3” is an ideal upgrade to replace small wattage incandescent or halogen lamps. No hot spot as with filament lamps. Simply connect a flexible glass fiber optic light guide to the LED housing and then provide a fixture to the upper or lower lamp port on your microscope. Here you will see the LED system connected to RetroFLUOR for incident light fluorescence studies.

This illumination is perfect for digital imaging and analysis … DC input, highly stable and very homogeneous across the entire sample field of view.

 

CONVERT YOUR MICROSCOPE FOR LED TRANSMITTED LIGHT FLUORESCENCE STUDIES – FRAEN




Here you will see a 30-year old Leitz Orthoplan along with the new FRAEN LED module. The yellow cube on top of the LED module aperture is used to illustrate the very uniform excitation beam as it enters the substage brightfield condenser. Here we use the existing condenser. Clearance between the dust window and the bottom of the condenser should be at least 40mm with the condenser set to Koehler and a slide in focus on the stage.

In the case of older Leitz microscopes, we make an adapter that secures the LED module in the dust window aperture and then held in place with the original lock-down bolt that comes with the microscope. No alignment, no problems. Just plug in the LED module to the electronic control unit (fixed or variable) and you are doing transmitted light fluorescence with long-life, efficient and homogenous LED illuminator. Put older microscopes to a new task or adapt your special support stand with this module and safely excite GFP for live organisms.

 

Microinjection devices for DNA / Transgenics and ESC procedures.

The image of the mouse egg (right) undergoing microinjection was imaged on a Leitz Diavert microscope with Hoffman Modulation Contrast. This unique optical system may be further researched by going to: www.modulationoptics.com.


REPLACEMENT LIGHT BULBS FOR MOST MODERN MICROSCOPE MAKES

Replacement BulbsWe stock just about every bulb made for use in Leitz and Wild microscopes. We also have a full line of replacement light 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 order is $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 micro3d@comcast.net 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 illuminator (i.e., "DDL", "EKE") and we can quote you a catalog number and price.


We have a good selection of new and used RMS 160/45 objectives from Russia, China and Germany. All objectives are strictly for use in transmitted light...including special Lomo objectives for strain-free polarized light studies. E-mail your specific requirements or questions.

DARKFIELD FOR STEREO/MACROSCOPES

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 in 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 with fiber optic ringlights. Not IRIS control lever in photo on LEFT...for contrast control of the darkfield. Shown in photo on RIGHT is the unit in position along with the Optem Zoom 160 macroscope (16:1). Bunton offers special high intensity darkfield illuminators complete with fiber optic light source for about $1,500.00. USA-made fiber optic transilluminators are available for all model stereo/macroscopes from Bunton.

 
  NOTE: We will include free rotating POL Filter with lens purchase…subject to prior sale*  


VIDEO/PHOTOTUBE . . . for MOTIC stereo microscopes as well as older M3, M5, M7, M8 models. Adapt your 35mm SLR, analog or digital camera. Photo tubes include dual iris for improved contrast and depth of focus. Shown with MOTIC model K400. .

 

CAMERA LUCIDA (Drawing Attachment). . . . . for MOTIC stereo microscopes as well as older WILD stereo microscopes. 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. Purchase a camera lucida with your MOTIC microscope and receive a free drawing board at no-charge.

 


NEW VOLPI USA LED VARIABLE ANGLE ANNULAR LIGHTING FOR USE ON STEREO MICROSCOPES AND MACROZOOMS

This new unit solves many lighting challenges. The portable remote control allows you to adjust intensity of the white LEDs (12) … this unit can also be used to turn on/off sectors of 3xLEDs at a time for dramatic effects and side lighting. The most important feature of this new unit is the ability to turn the outer adjustment ring and actually focus the LEDs for various working distances … 25mm to 150mm away from the lens. This compensates for the main limitation of fixed angle fiber optic ringlights.

Useable with LWD front lenses (0.5x) or with high aperture, short working distance front lenses (2x). A footswitch is available for rapid on/off control … useful for using the LED ringlight for focusing and composition and then bringing in epi-fluorescence with the Bunton Macrozoom FL … or a combination of both types of lighting!

Base unit with controller is $1850.00 Optional polarizer/analyzer kit to reduce glare from reflective samples or to increase contrast on many industrial specimen.

66mm inside diameter clamping ring. Adapters available for just about any microscope or macrozoom on the market.
