Pyro Radiometer
RM9-THz - mks Ophir (Ophir Photonics)
The RM9-THz radiometer is a sensor for measuring the power of very low level CW or quasi CW lasers and light sources. This sensor was specially designed for work in the terahertz range. The RM9-THz uses a pyroelectric sensor and lock-in amplifier with an 18Hz chopper (not included, use RMC1 or other chopper). The power range of the RM9-THz is from 100nW to 100mW, it has an 8mm aperture and covers the spectral range from 0.1THz to 30THz.
