Wedge prism has plane inclined surfaces. It deflects light toward its thicker portion. It can be used individually to deflect a beam to a special angle. Two wedge prisms work together can assembly an anamorphic prism to correct the elliptical shape of laser beam. The wedge prism is ideal for laser beam steering applications. By combining two wedges pf equal power in near contact and independently rotating them with angle deviation less than 10 degree, a ray passing through the combination can be steered in any direction with a narrow cone.It is applied to optical systems such as infrared imaging or monitoring, telemetry or infrared spectroscope.
