Broadband Neutral Plate Beamsplitters
Broadband Neutral Plate Beamsplitters
Product name : Broadband Neutral Plate Beamsplitters
Description :
● Spectrally flat performance over a broad wavelength range
● Equal (50 : 50) split ratio T and R
These low power beamsplitters have an Inconel alloy coating on the front surface and a broadband anti-reflection coating on the back. They split the beam by approximately equal reflection and absorption. Inconel has a spectrally flat reflectivity over the visible spectrum and considerably beyond that range making these beamsplitters useful for applications spanning visible and near infra-red wavelengths.
