Polarization spacer
106
Polarization spacer
This is a spacer and alignment ring that fits onto the laser collimator. It MUST be
used when inserting the collimator into an accessory optical input receptacle.
The ring has an alignment pin which aligns the polarization of the laser emission
properly with the accessory optics. As a spacer, the polarization ring positions
the collimator correctly in the optical input receptacle so that the interlock switch
of the input is engaged.
Note: Do not insert the collimator into an accessory without the polarization ring
installed on the collimator. Without the spacer, the input interlock switch is left dis-
engaged and emission is disabled.
