             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.

ANNOUNCING A NEW LED LIGHT SOURCE THAT IS AFFORDABLE AND EASILY MOUNTED TO REPLACE AN ARC LAMP

USA-MADE HIGH INTENSITY LED FOR EPIFLUORESCENCE MICROSCOPY - NO MERCURY...NO HAZARDOUS BULB CHANGES....EVER AGAIN!
THE PHOTO BELOW SHOWS OUR NEW LED ATTACHED TO A LEITZ PLOEM ILLUMINATOR.  AVAILABLE IN FOUR WAVELENGTHS (NEAR UV, VIOLET, BLUE AND GREEN) AND YOU USE THE EXISTING FILTER CUBES OR PURCHASE SPECIFIC FILTER CUBES FROM US TO MEET YOUR EXACT REQUIREMENTS AND FLUOROCHROME SPECIFICATIONS.  FILTER CUBES ARE CHANGED IN A MINUTE OR TWO. A NEW DUAL PORT BEAMSPLITTER IS AVAILABLE FOR THE ATTACHMENT OF TWO LED MODULES AT THE SAME TIME.

USA-MADE RETROFIT LED FROM KANSAS...www.retrodiode.com

RRR .... these 3D PRINTED modules are made to upgrade original "bulb" lighting that may be inefficient or inoperable after years of use. Bulbs become discontinued or hard to find. Sockets become corroded and in need of replacement. Circuit boards in 6V or 12V power supplies (internal or external) cannot be replaced or repaired. The RetroDiode solution is quite affordable (starts at about $160.00) and you never need to replace a light bulb again. All LED lighting has a constant color temperature and very even light distribution (no filament hot spot in the center). This makes the lighting very conductive to use with digital cameras. Easy to white balance and no need for shading correction. RetoDiode now makes a fan cooled high intensity model (20W) that is a superior replacement for the old 100W halogen bulbs. LED retrofit kits are available with 10W or 20W and all electronics are designed to eliminate any interference with digital or analog cameras. The 10W version is brighter than a 100W halogen lamp with 80A daylight blue filter at 10.5V.   20W version (photo #3 below) is highly recommended for polarized light, darkfield, DIC or phase contrast methods.  20W version (with micro fan) and controller shown (Orthoplan version) has a price under $350.00. Note the collector lens and ergonomic intensity controller for your placement in an easy-to-reach spot.  Do you have an old microscope with "dead" lighting? We can help .... just let us know the make and model and we will give you guidance on the solution.

EXTERNAL LED FOR WHITE LIGHT OR FLUORESCENCE STUDIES AT LOW MAGNIFICATION .... MADE IN AMERICA

Have you ever asked your microscope company if they offer a low magnification epifluorecence solution? Prices are beyond comprehension! We can offer you the fine www.nightsea.com products for use with microscopes ranging from student stereo dissecting microscopes to research photomacroscopes. The NIGHTSEA LED lighting is the perfect solution for off-axis lighting. The LED heads are easily interchangeable (BNC twist connector) so you can share the main power supply for the four or five important spectral "spikes".
Here you will see a great digital photography rig involving the Nightsea product. The USA-made  TS-160 (#1 below) is a compact microscope that can accept small or large format cameras (43mm diagonal full-frame sensors). The TS-160 comes with both a macro and micro front optic and features internal focusing. This is a microscope, not a zoom lens! It will focus from about 10mm to INFINITY. Mount it on a lab microscope stand or on your tripod in field. Aquatics, botanicals, genetics, materials science, geological samples etc. The new DIM base allows you to control the intensity level for routine ocular viewing or photomicroscopy.   We use optical glass barrier filters from Schott that are placed inside the microscope in front of the camera port...NOT in front of the lens. Use the Infinity Photo Optical KC for Z-STACKING WITH YOUR FAVORITE DSLR/MILC - FAR BETTER RESOLUTION THAN YOU COULD EVER EXPECT FROM USING A STEREO MICROSCOPE!
Prices start around $1,000.00  for one color module and controller unit. We also offer special versions to be mounted on gooseneck arms or articulated LED head carriers (#2 below) with remote wires for special lighting requirements. Battery power option for use in the field. Photo #3 below is the USA-made RetroDiode mounted on a Wild M20 to replace the original 6V20W lamp.....bulbs are no longer easily sourced! LED will go on for many years.


BUNTON'S OWN MICRO-MACRO EPIFLUORESCENCE VERTICAL ILLUMINATION

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 end that can be used with infinity-corrected macro objectives (IF-Series) as well as any infinity-corrected microscope objective.

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.

The cube housing has three 1/4-20 holes on the side for easy mounting to a stand of your choosing or design. Bunton will introduce a new heavy-duty microscope/camera support stand with the official launch of this system (Q4-2021). 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 housing.

NEW RetroFL INCIDENT LIGHT FLUORESCENCE MODULE WITH LED ILLUMINATION (PHOTO LEFT)

We have been building specialized microscopy systems for many years now.   Here you will see another support stand with heavy metal base and steel vertical post with focus drive.   On top of the cube housing (RetroFL) you will see a DUAL PORT beamsplitter that allows attachment of two cameras. The internal mirror is easily diverted for the vertical camera or horizontal mount.   The horizontal mount could also be fitted with a viewing ocular for composition and quick sample checks using the optical image seen by the camera.

Existing metal halide lamps using liquid light guides may be used with RetroFL. High intensity fiber optic illuminators may also be used with flexible fiber optic guides as shown in the photo to the RIGHT.
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.

RetroGON (Photo Below) is a 3D printed gizmo we designed for moving 3D objects (bugs, botanicals, small parts) by placing your sample on the rotating center disc and then making small theta rotations or adjusting pitch and yaw to bring the sample into the external lighting for illumination that looks best for the photo or z-stack sequence. The base is the same dimension as a glass slide (3x1") so it fits into any slide holder on an XY mechanical stage.  See RetroGON mounted on the XY stage directly above in the photo of RetroFOT. FREE WITH THE PURCHASE OF RetroFOT motorized Z-axis for stacking with your DSLR or MILC.
