We offer two models of motorized iris diaphragms, differing in aperture range. Both have 1.5 Inch Series flanges to couple directly to Oriel® Light Sources, and a 1/4-20 tapped hole in the bottom. Both models are driven by a fine resolution stepping motor located in the iris assembly, which can be commanded via a PC or the included controller (this controller can also control the 74041 Filter Wheel). RS-232 and IEEE-488 communications capability are included. Windows™ and LabView™ libraries of drivers and VIs allow easy control.
