Wedge Prism

Overview of Wedge Prism

Wedge prisms play a crucial role in laser beam control. They can operate alone, deflecting laser beams to specific angles; a single prism can shift the incident beam by one diopter (equivalent to a 1 cm shift over a 1-meter distance). Alternatively, they can be paired for beam deflection. Two wedge prisms can function as deformation prisms, correcting the elliptical beam output from a laser tube and deflecting the beam at different angles within a range of 4θ. By individually rotating the two prisms, beam shaping can be achieved, commonly used for beam scanning at different positions in imaging applications.

Feature of Wedge prism

Structural Features: The wedge prism has a beveled surface with a small inclination angle, allowing the optical path to deflect towards the thicker side of the prism. It is commonly used for beam control and deflection, enabling a single wedge prism to shift the incident optical path by a specific angle.

Application Characteristics: Wedge prisms are regarded as ideal devices for optical path adjustment in the field of optics. Two rotatable wedge prisms can adjust the direction of the outgoing beam within a certain range (approximately 10°). In laser technology, wedge prisms are often used for correcting laser beams, achieving precise alignment and positioning of the beam.

Materials and Manufacturing: Wedge prisms are typically made from optical glass or crystals, with the choice of material depending on the required optical performance and application needs. Their surfaces can undergo coating treatments to enhance specific spectral transmittance or reflectance.

Spectral Response: Certain wedge prisms, such as those used for infrared light, have specific spectral transmission ranges, for example, 2-12μm, making them suitable for infrared optical systems.
