Motorized Filter Wheel with RS232, GPIB or Pushbutton Control

The 74041 Motorized Filter Wheel holds up to six 1-inch diameter [25.4 mm] filters in individual mounts. A convenient access opening allows users to change filters without breaking apart the optical path. This allows the alignment to remain consistent even as the application needs evolve. The 74041 includes screw-in filter mounts, spanner wrenches for the mounts and filter retaining rings and a light blocking disk for dark measurements. The flange mounting provides a light-tight connection. It is suggested to rod mount the 74041 for additional support using its #1/4-20 mounting hole. The filter is selected via RS232, IEEE-488.2 (GPIB) or pushbutton control. Utility software is provided, as well as a command set for those wishing to create their own programs.
