Inexpensive, 5 and 8 position filter wheels
Motorized version available
Enclosed housing prevents light leakage
Hold 1 and 2 inch diameter filters or apertures
Attaches to 1.5 Inch Series flanges
These 1.5 inch series Oriel® flanged filter wheels are simple and inexpensive alternatives to motorized filter wheels when filter interchange is infrequent. They hold five or eight 1 or 2 in. (25.4 or 50.8 mm) diameter optical filters or apertures. A knurled knob at the top of the device rotates the wheel and indicates the filter in position. Each filter is positioned in the housing by a spring-loaded detent.
These filter wheels have the standard Oriel 1.5 inch series male and female flanges. They are intended, primarily, to mount directly to the input or output of Oriel components and instruments. However, they can also be post mounted.
The 1.0 inch (25.4 mm) models include a metal disk with absorptive paint acting like a shutter, for zero referencing.
