What is a wedge prism?

A wedge prism is an optical prism consisting of two flat surfaces inclined at a slight angle, designed to alter the direction of light. It is also called a "wedge-shaped prism" due to its geometry. This prism allows adjustment of the beam's angle without dispersing light, making it essential for applications in optical systems such as beam steering, wavefront correction, or laser alignment. It is widely used in laser devices, telescopes, and interferometers for precise beam control and optical axis adjustment.

Application of wedge prism

✅Laser beam adjustment
Wedge prisms are used to finely adjust the direction of laser beams, ensuring precision in optical system calibration.
✅Wavefront correction in interferometers
They control the wavefront of light in interferometers for precise measurements.
✅Optical axis alignment in telescopes
These prisms help align the optical axis, improving the accuracy of observations.
