Abstract
The present invention comprises a polarizer adhered on a flange plate at the top end of a L-shape base, an aslant surface on one side of the base, two sleeve screws protruded from the center of the aslant surface, an air duct defined between an upper base and a lower base of a Z-shape fixed base, two slots disposed on the lower base for receiving the sleeve screws, and two fixing bolts securing the washers onto the sleeve screw to limit the fixed base on the aslant surface of the base. A supporting surface is formed at a flange disposed downward at both ends of the upper base of the fixed base for gluing a half-wave plate. An adjusting mechanism protruded from the lower side of the fixed base extends into a recess at the lower end of the aslant surface; a screw hole is disposed on a side of the base and having an adjusting slot with its end propping one side of the adjusting mechanism; and an elastic member with its ends respectively fixed to a side of the base and a hole of the adjusting mechanism. The adjusting mechanism at the lower side of the fixed base adjusts the half-wave plate to an optimal polarized position.
