On the reflector turret (Fig. 4-20/9), select reflector module FL P&C with the desired fluorescence filter
combination (depending on excitation mode) and switch on.
Use the push-pull rod (Fig. 4-20/1) to swivel the desired LED (1 or 2) into the beam path.
When switching between the two LEDs the current brightness setting is adopted.
To avoid dazzling when switching between the LEDs, the brightness should be reduced slightly
beforehand.
Set the FL/TL toggle switch to position FL (reflected light fluorescence).
Adjust the light intensity for reflected light by turning the regulator (Fig. 4-20/3).
Finally, sharpen the image of the specimen.
