8.3.2 Assembly and operation LED versions: OCM 167 and OCM 168

Assembly
In order to put the fluorescence reflected light unit into operation, the following steps
have to be carried out.
1. The main body of the FL unit is already firmly connected with the microscope
housing and towers above the rear side of the microscope.
2. On this point the lamp housing must be mounted by help of two Allen screws.
3. Install the connecting cable between lamp housing and power supply unit.
4. Establish the power supply by attaching the mains cable.
5. Put the UV protective cover on the front edge of the stage.
6. Insert the slide for the beam path lock into the appropriate slot.
7. The LED lamps in the lamp housing are already installed.
Operation
Before you use the reflected light unit for special fluorescence applications, it will be
favourable to adjust the microscope in the bright field mode. This includes the placing
of the sample, adjusting the interpupillary distance, pre-focussing, dioptre adjustment,
etc. After that you can go on with the usage of the fluorescence reflected light unit.
1. When using the UV LED lamp, at first there must be ensured, that the beam path
lock has been activated (place the slide accordingly).
2. Establish the power supply.
3. Press the main switch.
4. After placing the sample, you can bring the needed objective into the beam path.
5. Set the required positions of the FL filter slide and the LED lamp slide (OCM 167) /
wheel (OCM 168).
OCM 167: Select between Blue and Green
OCM 168: Select between Blue, Green, Violet and Ultraviolet
The color of the selected filter must always be matching the color of the selected
LED lamp.
6. Now the beam path lock can be deactivated (place the slide accordingly).
