Non-Polarizing Beamsplitter Cube
Non-Polarizing Beamsplitter Cubes are precision optical components designed to split incident light into transmitted and reflected beams with minimal polarization dependence for imaging, laser and optical measurement systems. Using precision dielectric coating structures bonded between two high-quality optical prisms, these cubes provide balanced splitting ratios, excellent transmission performance and stable polarization characteristics. Chenyu Optics manufactures non-polarizing beamsplitter cubes in BK7, fused silica and custom optical substrates with non-polarizing dielectric, broadband and laser coating options.
Non-Polarizing Beamsplitter Cube Overview
Non-Polarizing Beamsplitter Cubes are precision optical components designed to split incident light into transmitted and reflected beams with minimal polarization dependence for imaging, laser and optical measurement systems.
By using precision dielectric coating structures between two high-quality optical prisms, non-polarizing beamsplitter cubes provide balanced splitting ratios, excellent transmission performance and stable polarization characteristics. They are widely used in laser systems, interferometers, imaging systems, optical instruments and scientific research equipment where consistent beam splitting performance is required.
Chenyu Optics supports custom non-polarizing beamsplitter cube manufacturing according to customer drawings, including custom splitting ratio, wavelength range, dimension and coating design for prototype and repeat production.
