FWM Series optical filter wheels provide a compact structure for translating from six to twelve, 1 in. (25.4 mm) diameter optical components up to 3 mm thick on a circular path to six discrete angular positions 60 degrees apart.
The base foundation has been designed to provide unobstructed optical paths for all six filters and standard optical heights of 25.4, 50.8, and 76.2 mm.
Three captured, spring-loaded index balls provide repeatable and wobble-free rotation of the filter wheel. An entire filter wheel can be removed simply by turning the center knob.
Individual filters can be mounted and safely held in place within the wheel by Newport\'s standard threaded Delrin retaining rings with a 23.7 mm clear aperture. This makes changing individual filters quick and easy.
