Prior Scientific has been a leading light in microscope illumination for many years. The chances are that if you’ve done any microscopy at all you will have used one of our light sources.

Lumen 200
Our flagship is the Lumen system for fluorescence illumination. This is an innovative solution which transforms fluorescence from a dark art to a cost effective, simple to use tool.

The Lumen 200 utilises a metal halide lamp rather than the more traditional high pressure mercury or xenon burners. This means 2000 hours of stable output compared to a maximum of 300 hours for a mercury lamp. Coupled to the microscope using a liquid light guide there is very little heat transfer helping to eliminate thermal drift during time lapse experiments. The Lumen 200 also incorporates a variable light attenuation control to reduce the potential of bleaching and phototoxicity.

Lumen 200PRO
For fully automated solutions the Lumen 200PRO features a motorised internal 6 position filter wheel for fast switching of excitation wavelength. Being remote from the microscope means no vibration. No vibration means no settling time. No settling time means faster imaging! The light attenuation and shuttering is also motorised in the Lumen 200PRO allowing a selection of intensity over 100 increments to perfectly balance exposure to the sensitivity of your cells and fluorescent markers.

LumenLED
The LumenLED system brings the advantages of LED illumination to fluorescence microscopy. LumenLED offers a choice of 10 LED wavelengths. These can be used in configurations of 2 LEDs or up to 4 LED wavelengths. On top of the specificity provided by LEDs they also provide long lifetimes which eliminates the need for bulb replacement and alignment. In addition, there is no transfer of heat or vibration to the microscope. LumenLED mounts directly to the microscope to maximise light intensity.
