FLI's color filter wheel’s robust mechanical design provides the basis for stunning, uncompromising images. Each FLI color filter wheel is precision engineered with a highly accurate no-slip drive chain and stepper motor. The large diameter pivot pin and bushings are precision ground and matched for smooth, quiet no-fuss operation night after night. FLI color filter wheels do not use internal lights for homing, so your images are protected from stray light interference.
