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

Today the 150W halogen reflector bulb with short lifetime has been replaced by the LED. We sell the USA-made LED systems from www.scopeled.com. The B-SERIES lamp (shown below right) is easily attached to most modern microscopes with a suitable adapter. This is an efficient, high intensity unit with adjustable collector lens. It is a perfect solution for incident or transmitted light methods such as darkfield, DIC, phase contrast or polarized light.

Take a look at the F-SERIES LED for incident light fluorescence studies where you already have the Ploem illuminator and filter modules. The F-SERIES allows the user to optimize the excitation spectra to the filter cube and fluorochrome being used. Dial in near UV (violet), blue-violet, royal blue or green light as needed.

The ScopeLED G-250 SERIES uses a LED light source that is used with fiber optic light guides such as the reliable "dual gooseneck" or "ringlight" for shadow-free annular darkfield illumination of opaque samples. G-250 may also be customized for use with the flexible fiber optic guide and then connected to optical systems such as the Leitz ULTROPAK or special workstations requiring the light to be transmitted to the microscope via glass fiber optic or liquid light guide.

METAL HALIDE LAMPS .... we use the UK-made Prior metal halide lamps with light liquid guides (center photo below). These lamps have a much longer lifetime than the old HBO 100W mercury arc burner. The liquid light guide is a very efficient method to bring the light into the microscope port for fluorescence studies. Spectral distribution (spikes) are similar to HBO 100 mercury arc.

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 unuseable 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 $150.00) 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. Options exist to retrofit the LED illumination to an existing microscope condensor lens and lamp housing. Other options include total lamp replacement with the collector lens built into the LED module itself. 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. Prices start around $1000,00 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.



Do you need a LED solution for microscopy? We can also offer our own macro/micro optical system for INTRAVITAL STUDIES or INDUSTRIAL INSPECTION. Give us a call.

BUNTON'S OWN MICRO-MACRO EPIFLUORESCENCE VERTICAL ILLUMINATION

Here is the Bunton-built MacroZoom FL (black square single cube holder with fiber optic guide port) that originally used the OPTEM (USA) zoom back end and macro objective holder on the front end. Note that a Marzhauser stepper motor stage is used to move the sample X/Y. Such zoom systems can be useful for quick magnification changes but image quality may be compromised if the numerical aperture of the front end objective is insufficient. Remember a good microscopy rule....never exceed 1000 x the n.a. or you will end up with "empty magnification" that makes things larger but no improvement in resolution. We anticipate such systems to be improved substantially with high n.a. microscope objectives with required working distance specs...and the Infinity KC will replace the Optem Zoom 125 shown in the photo. Special versions of the RetroBOT XYZ can be used with such systems....to include z-axis fine focus motorization for Z-STACKING and XY STITCHING capabilities. Custom configurations are available....contact Jim Averill so we can tell you more about this unique system.

We have been building specialized microscopy systems for many years now. We make a filter vertical illuminator (black module with fiber optic connection) that accepts a single Chroma filter cube. The fiber optic can be connected to a halogen lamp, metal halide lamp (with liquid light guide in place of fiber optic guide). We use the USA-made Infinity Photo Optical KC microscope front end....accepts macro or micro objectives. An option for both a Peltier cooled camera and a DSLR or it could be used with a visual ocular for set-up and composition of the subject. Contact us for more details and check out our YouTube demos....look for RETROFLUOR 2.

                            FLASH, LED, FIBER OPTIC POINT SOURCE OR RINGLIGHT?


TWIN FLASH HEADS MOUNTED ON A DIY BASE IS A GREAT LIGHTING METHOD FOR PHOTOMACROGRAPHY AND Z-STACKING....THE LIGHT GETS INTO THE "NOOKS AND CRANNIES" AND IS EASILY INITIATED WITH A DSLR CAMERA AND RETRO-ZED. NOTE THE FLEXIBLE GOOSENECKS...NIKON AND CANON MAKE SUCH COMPACT FLASHHEADS THAT ALSO HAVE LED MODELING LIGHTS INTEGRATED. 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. WE CAN TELL YOU MORE ABOUT FILTERS, POL FILTERS, COLLECTOR OPTICS AND SOFT LIGHT CREATION IF YOU ARE INTERESTED....JUST DROP US A NOTE OR SEND US YOUR SAMPLES FOR A PHOTO SESSION HERE AT OUR SHOP. WE THEN RETURN YOUR SAMPLES AND JPEG IMAGES BY EMAIL. YES, WITHOUT PROPER LIGHT FOR THE SAMPLE YOU WILL END UP WITH UNUSEABLE PHOTOS....WYSIWYG!
