THz High Resistivity Silicon Beam Splitter

Thz High Resistivity Silicon Beam Splitter

The material of the terahertz beam splitter is generally a high-resistance silicon wafer. The polished high-resistance silicon wafer has the function of transmitting terahertz and anti-visible light and has the function of transflective and translucent to terahertz waves, and the light splitting ratio is about 6:4(through:60%, opposite40%). Mylar film can achieve a higher splitting ratio(5:1).

An addtional AR coating can be applied up on request, we have 4 Terahertz AR coatin, Splitting ratio can improve to 90:10, the coating peak wavelength are 2.7Thz, 3.4Thz, 3.8Thz, 4.5Thz.
