*Laser Thermal Power Sensors
Thermal sensors have a series of bimetallic junctions called a thermopile. Radial or axial heat flow through the sensor creates a voltage proportional to the power absorbed as it flows through the thermopile. The reading is not dependent on the ambient temperature since only the temperature difference is measured and not the absolute temperature. The thermopile elements are so arranged that the reading is almost independent of beam size and position. Generally, Ophir specifies ±2% or better uniformity of reading over the surface.

Pyro Radiometer
RM9-THz
-
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.
