Brewster Prism
Brewster Prisms are precision optical components designed to minimize reflection losses and control polarized light transmission by utilizing Brewster angle principles in laser and polarization optical systems. Manufactured from fused silica, BK7 optical glass, sapphire and custom optical substrates with precisely designed prism geometries, these prisms provide efficient p-polarized light transmission without requiring additional coatings on the Brewster surface. Chenyu Optics manufactures Brewster prisms uncoated or with AR and broadband AR coatings for laser, polarization control and spectroscopy systems.
Brewster Prism Overview
Brewster Prisms are precision optical components designed to minimize reflection losses and control polarized light transmission by utilizing Brewster angle principles in laser and polarization optical systems.
By using high-quality optical substrates with precisely designed prism geometries and Brewster angle surfaces, Brewster prisms provide efficient p-polarized light transmission, excellent polarization performance and stable optical characteristics without requiring additional coatings on the Brewster surface. They are widely used in laser systems, polarization control systems, optical cavities, spectroscopy equipment and scientific optical instruments where low-loss polarized light handling is required.
Chenyu Optics supports custom Brewster prism manufacturing according to customer drawings, including custom prism angle, material and dimension design for prototype and repeat production.
