Broadband Beam Splitter

Our broadband non polarizing hybrid cube beamsplitters are ideal for use with multiple lasers or tunable sources.

Broadband beam splitter. Beamsplitters are also ideal for fluorescence applications optical interferometry or life science or semiconductor instrumentation. 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. 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. Ito front surface optimized for 1 120 thz ar coated back surface for visible wavelengths.

A dielectric coating provides long term stability. Incoming beams are both transmitted and reflected 45 with the s and p polarized components matched to within 10. Even power split ratio insensitive to polarization broadband and chromatically neutral. Light can be split by percentage of overall intensity wavelength or polarization state.

Thorlabs polarizing beamsplitting cubes are offered in six sizes and with five beamsplitting coating ranges. Beamsplitters are common components in laser or illumination systems. 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.
