THz Beamsplitter
Product Introduction
Tera photoelectric Technology offers two different specifications of THz beamsplitter
Single-pass beamsplitter: used in optical schemes where radiation passes through the beam splitter only once
Multiprism beamsplitter: used in interferometer configurations, where the light beam needs to pass through the beam splitter multiple times

The material of the THz spectroscope is HRFZ-Si. These spectrometers can transmit/reflect light within a wide wavelength range without any coating, and the transmission/reflectance ratio is approximately 54/46 (%).
The reflectance and transmittance curves are shown in the figure:
