5.7 Equipping the Incident Light filter turret

The receptacles on the turret are numbered. According to your equipment, the individual filter and/or reflector cubes have already pre- assigned positions. A list is provided along with your shipment (“Identification Sheet”).

Insert the filter and reflector cubes in the follow- ing manner:

•Equip the incident light turret only when the microscope is switched off.

•Remove the face plate from the upper part of the microscope (Fig. 25). Turn the turret in any direction until the locking pin engages.

•Insert the filter or reflector cube into the mounting in front of you according to the identification sheet provided.

To do so, place the filter or reflector cube on the right side and press it to the left into the mounting (Fig. 26).

•Push the retention pin (25.2) and continue to turn the filter turret until you reach the next locking position.
