Manual, coded or motorized reflector turret 6-
position (Fig. 57/22)
− Can be loaded with a maximum of six reflector
modules for reflected light fluorescence
− Manual, coded reflector turret: Rapid reflector
change by rotating the adjustment ring. The
activated reflector is marked by a line on the
right of the reflector turret
− Motorized reflector turret: Rapid reflector
change e.g. by using the pair of buttons on the
right control ring (Fig. 77/1)
Dual filter wheel mot. for beam splitting and
emission; CAN
− Observe the Quick Reference Guide 452358-
7044-001 for the operation of the dual filter
wheel mot.
Manual or motorized focusing drive, right side (Fig. 57/23)
− Coarse focusing drive approx. 2 mm/revolution and fine focusing drive approx. 1/10 of coarse/fine
focus transmission ratio
− Total travel approx. 10 mm, 13 mm also possible
− Coarse adjustment (large knob), fine adjustment (small knob)
− Optional: Fine drive, flat right or left, stand 5 materials always flat-left (already included in stand)
TL button (Fig. 57/24)
− Pressing briefly switches the halogen or LED illuminator on or off. If a transmitted light shutter is built
into the carrier for transmitted-light illumination, it will be opened or closed alternately
− Pressing and holding down for > 1 s sets the brightness to the 3200 K value for color photography
RL button (Fig. 57/25)
− Pressing briefly (< 1 s) activates or deactivates the external or internal fluorescence shutter (reflected
light) alternately
Control wheel for illumination intensity control of the microLED, HAL 100 or Colibri 7
illuminator (Fig. 57/26)
− Controls the brightness of the microLED, HAL 100 or Colibri 7 illuminator
− Adjustable voltage range from 0 to 12 V
− The maximum is limited by a stop on the 3, 3 materials stand
− On the 5, 5 materials and 7, 7 materials stands, an acoustic signal sounds when the maximum
brightness is reached. The rotation of the control wheel is not limited by a stop in these stands
