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 (PHOTO #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. BLUE LED FOR MICROPLASTIC FLUORESCENCE (NILE RED) STUDIES.  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.

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). Delivery will begin Q1-2022. 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.  Older Leitz lamp housings accepted on trade-in.....no mercury sockets or older power supplies needed!  Save a few bucks and go LED with a trade-in allowance.

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.

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.

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

We have been building specialized microscopy systems for many years now.  The RetroFL 3D-printed module (RIGHT) is our third generation prototype. It is designed for functionality, easy filter module and LED interchange and light weight. We use the special enlarged cubes from Chroma and any filter sets in their catalog may be used with RetroFL.  Note the exciter filter of a GFP "cube" inside the RetroFL. This is the interchange illumination port. The black metal adapter on top receives the Infinity Photo Optical KC microscope. The front lens is then mounted on the bottom of the RetroFL module in another metal threaded mount. The third photo at the end of this page shows our two earlier versions of RetroFL. The easily interchangeable fitler cubes and LED modules make this a very unique tool.

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.

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.
