The emission filters are located on a filter wheel behind the lens. A filter wheel can hold up to
five filters with a diameter up to 50 mm using specific filter holder inserts.
An illustration of the filter wheel is given below (filter wheel shown from above).
The positions of the filters are numbered and identified by a respective number printed on the
filter wheel.
For luminescence and photographic measurements filter position 5 must be open. Using emis-
sion filters the inprinted arrow on the filter should face the sample, turning away from the cam-
era.
To insert the filter slides switch off the NightSHADE, open the filter flap at the front side of the instrument,
move the wheel manually to the required position and slide in the filter holder.
After moving the filter wheel manually it is required to initialize the wheel again. Otherwise the filter posi-
tioning might be wrong. It is recommended to change filters on the filter wheel while the instrument is
turned off.

indiGO supports an integrated filter management. The filter management is used to describe the
filter charging on the excitation filter sliders as well as the emission filter wheels.
