KG Filter Wheel LH_MO02
The KG filter wheel consists of two paddles:
− The 1 st paddle (A) is linked rigidly with the motor
shaft by a toothed belt.
− The 2 nd paddle (B) is fastened on the motor shaft
and can be turned.
Both arms are linked by a spring which presses the
KG5+IR-IV filter against the stop.
The paddles can be pushed into the light path up to
a stop, the light sensor LH_LS02 being covered.
This is the starting position (KG+IR-UV filter in the
light path).
When the paddles are moved out of the light path
by one filter position, the RG850 filter is in the light
path. This filter is used for the Infrared Scan.
When the filter is moved into the light path from the
initial position, the first paddle moves (with the light
dimmer) into the light path against the spring
mechanism. In this position, two filters are in the
light path: The KG+IR-UV filter and the light dimmer.
Filter Positions
When the filter is out of the light path, the light
sensor is uncovered. When the KG+IR-UV filters is
moved in, the light sensor (2) is covered. If the
motor continues to turn, the KG5-IR+UV filter is
pressed against the stop (1) by a spring, the light
dimmer is moved in.
