Wedge Prism
Wedge prisms are precision optical components with a small angular wedge between two optical surfaces. They are designed to provide controlled beam deviation while maintaining high transmission and optical stability. By adjusting the wedge angle, wedge prisms can precisely control beam steering and optical path alignment.
Wedge Prism Overview
Wedge prisms are precision optical components with a small angular wedge between two optical surfaces. They are designed to provide controlled beam deviation while maintaining high transmission and optical stability.
By adjusting the wedge angle, wedge prisms can precisely control beam steering and optical path alignment. They are widely used in laser systems, interferometry, optical measurement and imaging applications.
Chenyu Optics supports custom wedge prism manufacturing according to customer drawings, including custom wedge angles, dimensions, angular tolerances, surface accuracy, edge treatment and coating design for prototype and repeat production.
Key Advantages of Wedge Prisms
