             optimized illumination is half the battle.......

BUNTON OFFERS A WIDE SELECTION OF MICROSCOPE ILLUMINATION SOLUTIONS.....LED IS RAPIDLY REPLACING THE INCANDESCENT LIGHT BULB AS WELL AS ARC LAMPS THAT HAVE BEEN USED FOR THE PAST 40 YEARS IN FLUORESCENCE MICROSCOPY
Please feel free to contact us with your exact requirements for lighting. We are specialists in adapting new LED illumination for older, existing legacy microscopes. Constant color temperatures and very even illumination. New products now can provide special illumination that was not possible in the past. Transmitted illumination as well as incident light illumination is now optimized using LED modules.

We know of one little 5W bulb for microscopes that has been discontinued....very hard to find these incandescent bulbs. Ebay sellers are having a field-day gouging the marketplace for a bulb that used to sell for $1.00. Look for this bulb selling at the moment for $20-60.00...EACH! Switch to LED and never change a bulb again.

BUNTON'S OWN MICRO-MACRO EPIFLUORESCENCE VERTICAL ILLUMINATION - RetroFL

Bunton is soon to launch the new RetroFOT-Z with our RetroFL attachment for incident light fluorescence studies and z-stacking. This unique system features the USA-made Infinity KC VIDEOMAX microscope front that can be used with infinity-corrected macro objectives (IF-Series) as well as any infinity-corrected microscope objective...Infinity Achrovid, Mitutoyo M26 thread or any of the NOZL firm industrial objectives for your specific lighting requirements.

NOTE:     Here is our prototype RetroFL with the blue light LED attached. Use with just about any camera including Peltier-cooled models (as shown LEFT).  Contact us for further details, questions or price quote.  The LED you see is made in the USA and sells for about $1,000.00 plus an adapter for your microscope make and model.  

The USA-made LED illuminator you see here is offered with 400, 450, 500 and 550nm LED matrix and collector lens. Intensity can be easily adjusted to your exact requirements with the control knob shown on top of the heat sink metal housing.   Filter cubes and LED sources are quickly exchanged as needed for different fluorochromes.  Very reasonably priced!

The KC features internal fine focusing and an aperture diaphragm. Long working distance lenses make this system ideal for intravital studies as well as for fluorescence of embryos and larger organisms that would not be suitable for regular compound microscopes.  Ideal setup for the imaging of MICROPLASTICS in water samples and seafood.  Coaxial fluorescence microscopy with digital imaging and software for measurements, counting and report documentation. This system (RetroFL) provides much better results than a routine stereoscopic microscope with a camera mounted on one of the two optical channels.  Micro or macro front optics...interchangeable filter cubes and LED modules. High mag objectives for the study of MICROALGAE and MICROFLUIDIC fluorescence experiments and slow motion recordings using a high frame rate, global shutter camera.

Filter cubes are quickly exchanged with the removal of screws.  25mm filter dimensions provide a very wide field of illumination and the LED matrix is quite homogeneous over a 20-30mm field depending on placement of the lamp in the illumination port.  A collector lens is built into the LED ILLUMINATOR.   Contact BUNTON for a price quote on the KC-RetroFL with LED illumination.

The PHOTO TO THE RIGHT shows the USA-made HIGH INTENSITY WHITE LED mounted on an older Leitz industrial microscope with Modul-OPAK vertical illuminator.  Two versions for just about every existing microscope with an upper lamp port. These lamps use a white light LED and are not intended for use in fluorescence microscopy. The STANDARD and HIGH INTENSITY models are intended for those who need increased intensity and all of the benefits of using LED instead of the older quartz halide lamps ranging from 20W to 100W. Constant color temp at all intensity levels, no hot-spot...very homogeneous illumination. 90% less power consumption and no expensive (or obsolete) tungsten filament bulbs.

We presently offer LED single spectra illuminators for ROYAL BLUE and GREEN excitation. This is a perfect modular solution for the study of NILE RED stained MICROPLASTICS found in our waters and fisheries.    NILE RED is excited with the 450-480nm ROYAL BLUE.   Such lighting and filter cubes are also useable for GFP and FITC.   The INFINITY KC microscope is then attached along with your camera of choice.   Software for Z-STACKING or IMAGE ANALYSIS can then be used to meet your exact requirements.   MICROPLASTIC MICROSCOPY involves plastic particles 5MM OR LESS.  The KC microscope can be easily converted from MACRO to MICRO for single digit MICRON SIZED particle imaging and identification. NEW FOR 2023....MODULAR LED FOR NUV EXCITATION IN THE 370NM RANGE.   CONTACT US FOR A CUSTOM-MADE RetroFL WITH KC-VIDEOSCOPE TO MEET YOUR RESEARCH REQUIREMENTS.  USE YOUR EXISTING INFINITY-CORRECTED OBJECTIVES INCLUDING MITUTOYO AND SPECIAL NOZL OPTICS FOR LONG WORKING DISTANCE AND HIGH N.A.

WE WILL SOON HAVE A MULTI-SPECTRA LED ILLUMINATOR WITH LIQUID LIGHT GUIDE AVAILABLE FOR USE WITH RetroFL. Affordable and perfect for intravital microscope configurations where a heavy lamp housing connected to the main microscope would be unsatisfactory. Stay tuned. Contact me if you would like to be kept informed of our coming LED products.

This is an ideal set up for intravital microscopy on live animals. Such systems can also be used for the study of art objects and paintings.   Industrial inspection of wafers (contaminants and excess photo-resist) can be identified easily with a fluorescence microscope. Special XY stages are available for large samples or XY movement of small animals etc.  

                            FLASH, LED, FIBER OPTIC POINT SOURCE OR RINGLIGHT?


LED MODULES MOUNTED ON A FLEXIBLE GOOSENECK ARE THE PERFECT SOLUTION FOR PHOTOMACROGRAPHY ILLUMINATION...THE LIGHT GETS INTO THE "NOOKS AND CRANNIES" AND IS EASILY INITIATED WITH A DSLR CAMERA AND RETRO-ZED. SHADOW-FREE ILLUMINATION OF 3D OBJECTS IS THE BEST LIGHTING SOLUTION...BUT SOMETIMES YOU WANT SHADOWS. A SERIOUS PHOTOMACROGRAPHER WILL HAVE BOTH RING ILLUMINATION AND POINT SOURCE LIGHTING (FLASH OR GOOSENECK TYPE) AT THEIR DISPOSAL.
