Broadband Beam Splitter

Even power split ratio insensitive to polarization broadband and chromatically neutral.

Broadband beam splitter.

These broadband versions are designed to handle average powers up to 500 watts for wavelength ranges of 400 700 nm 700 1000 nm 900 1300 nm or 1200 1600 nm. Thorlabs polarizing beamsplitting cubes are offered in six sizes and with five beamsplitting coating ranges. These cubes separate the s and p polarization components by reflecting the s component with the dielectric beamsplitter coating while allowing the p component to pass. Beamsplitters are common components in laser or illumination systems.

Your one stop source for beamsplitters. Light can be split by percentage of overall intensity wavelength or polarization state. The va cb series is based on zero order half waveplates and polarizing cube beam splitters. Thorlabs 50 50 uv fused silica broadband beamsplitters which are available in ø1 2 ø1 25 mm x 36 mm and ø2 versions have a beamsplitter coating for the 250 450 nm range deposited on the front surface that has been optimized for a 45 angle of incidence.

Beamsplitters are also ideal for fluorescence applications optical interferometry or life science or semiconductor instrumentation. Incoming beams are both transmitted and reflected 45 with the s and p polarized components matched to within 10. A dielectric coating provides long term stability.
