Filter Change in the Detection Beam Path of Channels 1 and 2
For optimum investigation of specimens it is useful to employ filter wheels permitting the motor-
controlled change between different filters for narrow-band or broad-band detection depending on the
wavelength. The number of filters is limited by the capacity of the filter wheel. The change of the filter
wheel as a whole involves complete readjustment.
The filter wheels of channels 1 (upper cover cap) and 2 (lower cover cap on the right side) of the
Scanning Module have a change position in which a filter, including its mount, can be changed in a
reproducible position without requiring readjustment. The filters can be rotated in their cells, and with
the light path being eccentric relative to the filter center, the best transmission area of the filter for the
respective wavelength or pass range can be found by rotating the filter. This is very important for the
investigation of specimens of low emission.
Filter change
•
By software control, move filter wheel (8-3/
5
) to
the change position.
•
Pull cover cap (8-3/
1
) off the Scanning Module.
•
Use the filter tool (8-3/
2
) to pull the filter mount
(8-3/
4
) with the filter (8-3/
3
) out of the guide
well.
•
Change filter to suit the application.
The filter can be rotated in its mount,
allowing adjustment for finding the best
transmission area of the filter for the
wavelength used.
•
Enter the designation of this particular filter into
the System Software database.
