Inserting the fluorescence module

The fluorescence module (Fig. 26) is part of the fluorescence stand, but is also available as a retrofit kit. To retrofit the fluorescence module, remove the blind cover from the stand. The fluorescence module can be fitted with up to four different filter cubes (26.3). They are inserted into the dovetail mount (26.2) of the fluorescence module with their engraving facing downwards (towards the turret plate). The fluorescence module is inserted on a dovetail guide into its slot on the stand by pushing it as far as the stop. One part of the fluorescence module is the anti-glare protection (27.1), which can be inserted between the tube and the stage. Proceed in the same way if you are inserting a motorised filter cube changer instead of the manual filter module. Also read the manual for the electronic version.

Assembly of the lamp mount, mirror housing, lamphousing, illumination telescope

1.Insert the lamp mount or mirror housing in the back panel and screw down with Allen screws. Engage the guide pin of the lamp mount (29.1) in the back panel of the microscope stand (28.2).

2.Hold the lamphousings 107/2, 107, 106 z against the lamphousing mount and secure with the fixing screw (Fig. 31).

3.We recommend using the illumination telescope for gas discharge lamps. This is inserted between the lamp mount and the lamphousing 106 z (30.4) and magnifies the image of the focal point of the lamp by the factor 2x in the entrance pupil of the objective. This results in a significantly higher illumination intensity for fluorescence.
