Glass Wedge Prisms

Glass wedge prism is a basic optical lens with a tilt angle, which can deflect the light path to the thicker side. The larger the wedge angle, the larger the deflection angle. Glass wedge prisms are mainly used to control beam deflection and scanning. They rotate along the optical axis. Glass wedge prisms can achieve circular scanning output of beams. Two glass wedge prisms are used in combination to control the relative rotation speed of each other, so that the beam can be output in any shape. The processing technology of Tianyanggu glass wedge prisms is mature and it is easy to achieve high-precision dimensions. The precision of prisms with a size of less than 3 inches can be controlled within 3 seconds. Glass wedge prisms are processed through milling, fine grinding, grinding and polishing processes to achieve high-precision mirror flatness and angle accuracy.
