N-BK7 and Fused Silica Wedge Prisms and Wedge Windows

Wedge prism is an optical element with an inclined plane that deflects the optical path toward the thicker side, so a single wedge can offset the incident beam by a small angle. When two wedges are combined, they form a Risley prism pair that can correct a laser beam or adjust the direction of the outgoing beam within a certain range — an ideal beam-steering device.

N-BK7 and Fused Silica Wedge Prisms and Wedge Windows

 

Product Overview：A wedge prism, also known as a wedge-angle prism, is an optical element with inclined bevels that deflects the optical path toward the thicker side. It has a function similar to that of optical windows, and both can be used as isolation components. Wedges produce a small deviation, so the beam does not return to the source.

Scope of application：

1. Optical imaging: corrects monochromatic and chromatic aberrations, improving imaging quality and making images clearer and more accurate.

2.Laser technology: used to adjust the direction and angle of the laser beam for precise beam pointing control.

3.Optical measurements: wedge prisms can be used as important optical elements to generate optical path differences.

4.Optical communication: adjusts the propagation direction of optical signals to enable switching and coupling between different optical paths.

5.Scientific research: used to construct various optical experimental setups to study the polarization characteristics of light and the laws of refraction and reflection.

High Purity Equilateral Prisms And Dispersive Prisms
High-quality Optical Glass Equilateral Prisms And Dispersive Prisms
Equilateral prisms have three equal 60° angles. Thanks to their geometry and optical properties, which separate light of different wavelengths, they are often used as dispersive prisms and are widely applied in spectral analysis and other fields. Dispersive prisms are usually triangular in cross-section. Because different wavelengths of light are refracted at different angles in the same material, they can decompose polychromatic light into monochromatic light, playing a key role in spectrometers, optical parametric oscillators, and other instruments.
