Broadband Neutral Plate Beamsplitters (BNEB)
- Extremely neutral over visible spectrum
- Low power applications
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.
