Motorised filter wheel 12x12.5mm

The motorised filter wheel from Andover, driven by a stepper motor and controlled by an optical encoder, is designed for repeated selection of filter positions: either by manual push button command or remotely via the RS-232 or USB 2.0 interface! The filter wheel has two aperture positions at 12:00 and 9:00 o'clock and has a digital display on the instrument that shows the current filter position. The integrated filter holder with twelve positions can hold up to twelve ½" filters (12.5 mm).
