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.

Broadband beam splitter.

The va cb series is based on zero order half waveplates and polarizing cube beam splitters. Ideal for beam combining or separation the substrate is made of high quality n bk7 glass with the front surface optimized for terahertz wavelengths and the back side coated with a broadband antireflection coating optimized for visible wavelengths. Thorlabs polarizing beamsplitting cubes are offered in six sizes and with five beamsplitting coating ranges. Beamsplitters are common components in laser or illumination systems.

A dielectric coating provides long term stability. Beamsplitters are also ideal for fluorescence applications optical interferometry or life science or semiconductor instrumentation. Ito front surface optimized for 1 120 thz ar coated back surface for visible wavelengths. 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.

Incoming beams are both transmitted and reflected 45 with the s and p polarized components matched to within 10. 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. Our broadband non polarizing hybrid cube beamsplitters are ideal for use with multiple lasers or tunable sources.
