Microscope: Illumination

Main light lntegrated LED illumination system for intensive, uniform illumination of the field of view.
Coaxial red reflex Illumination  The two precision-formed halogen bulbs 12 V / 50 W of the OttoFlex illumination generate a clear and stable red reflex, decreasing stray light through the sclera and increasing the image contrast. Lamps can be changed effortlessly and quickly.
Retina Protection Function Reduce the main light up to 10% and OttoFlex up to 20%. When the user deactivates the function, the light levels will go back to previous intensity.
Filter Built-in UV-protection, 400 nm
