Broadband Beam Splitter

Your one stop source for beamsplitters.

Broadband beam splitter.

A dielectric coating provides long term stability. Even power split ratio insensitive to polarization broadband and chromatically neutral. 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.

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

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. 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.
