Products description

Imagine a fluorescence microscope that needs a lamp change every 50.000 hours.
Imagine a fluorescence microscope with a cold light source that barely heats up during use.
Imagine a fluorescence microscope that can be switched on, used immediately, switched off and then back on again.
Imagine a fluorescence microscope that is so safe as to need no protection shield whatsoever, and that can be used by anyone, without any
specific precaution.
Imagine a fluorescence microscope that can be powered by batteries, as easily as a torchlight.
Imagine a fluorescence microscope that is so sturdy and so compact that it can be used on the field, with any transport problems.
You may think that such an instrument exists in your imagination only. Actually, such microscope is real, and its name is OPTIKA B-350LD.
Developed by the OPTIKA Research labs, B-350LD marks a revolution in the field of fluorescence microscopy.
Strictly derived from model B-350FL, from which it shares the body, the optics and the filter sets, B-350LD employs high-power LED’s instead of
the classical mercury vapour lamp. The LED’s are tailored to the specific applications (FITC-TRITC).
The brightfield illuminator uses our X-LE DTM system, and the colour temperature closely matches sunlight.
The microscope is available in two versions: B-353LD1 and B-353LD2
