This object contains two pieces. There is an outer 7/8" high cylinder and a inner piece with a circular plate that has a small solid cylinder in the center, and two sets of three connector holes on two sides. Both of the sets of three have wires without insulation. Underneath this is a ceramic U-shaped frame with single silicon chip mounted on a small metal bar. There is a paper label on the plastic container box which says, "Special for 304 Collimator(?) OD160-1 material."
