Motorized Variable Two Wheel Attenuator 991-0602 consists of two filter wheels. Each wheel contains eight filter mounts of ØD with a clear aperture of Ød mm. Each mount is inclined by 4° to prevent mutual reflections between filters.
We supply 991-0202-01 attenuators with a standard, most popular, set of filters. See the table below. Alternatively, optics can be manufactured according to individual orders. Or we can supply the attenuators without filters, which you can fit by yourself. Bring a filter of each wheel into the optical path easily by hand or using automation. Two wheels are driven by a single step motor. A computer can operate it via controller. The Step Motor Controller Card 980-0040-USB/ 980-0030-RS232 and Position Control Software come separately. For fastening, attenuator has clearance slots for M6 and M4 screws. There are also two M6 holes, and one M4 hole (opposite to one of the M6 holes).
