What is an optical prism called a wedge prism? How does it work? Wedge prism, also known as wedge angle prism, is an optical device with an inclined plane.
Wedge prisms are mainly used in the optical field for beam control offset. The inclination angle of both sides of the wedge prism is relatively small, which can cause the light path to deviate towards the thicker side. If only one wedge prism is used, the incident light path can be offset at a certain angle. When two wedge prisms are combined, they can be used as deformable prisms, mainly for correcting laser beams. Wedge prisms are an ideal optical path adjustment device in the field of optics, where two rotatable prisms can adjust the direction of the outgoing beam within a certain range (10 °).
Wedge prisms can also be used to individually deflect laser beams to a certain angle, or to combine two wedge prisms as beam deflection applications. A single prism can offset the incident beam by a certain angle. If measured with diopter, it is one diopter, equivalent to a deviation of 1 centimeter at a distance of 1 meter. Two wedge-shaped prisms can be used as deformable prisms (to correct the elliptical beam output by the laser tube) or to adjust the beam between 4 θ Deflection at various angles within the range, θ It refers to the light that is deflected by a single prism. This beam shaping is achieved by rotating two wedge-shaped prisms separately, typically used for beam scanning at different positions in imaging.
Two wedge-shaped prisms can be used as a pair of deformable prisms in beam shaping applications (to correct the elliptical beam output by the diode). Alternatively, it can be used to deflect the beam at various angles within the full angle 4T range, where T refers to the light that is deflected by a single prism. This beam deflection is achieved by rotating two wedge-shaped prisms separately, and is typically used in imaging applications to scan different positions of the beam.
