100 nW to 100 mW Pyroelectric 0.1-30 THz Radiometer
100 nW to 100 mW Pyroelectric 0.1-30 THz Radiometer
The RM9-THz pyroelectric 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 18 Hz chopper (not included, use RMC1 or other chopper). The power range of the RM9-THz is from 100 nW to 100 mW, it has an 8 mm aperture and covers the spectral range from 0.1 to 30THz.
- Pyroelectric sensor with 0.1 to 30 THz spectral range
- 100 nW to 100 mW power measurement range
- Use RMC1 or other chopper and lock in amplifier for lowest noise and drift
- 8 mm diameter aperture See All Features

How to Measure Power of TeraHertz Beams
THz radiation is being talked about more and more lately, because of its unique usefulness in a wide range of applications. In this video you will learn about some of these applications, and about a range of solutions Ophir offers for measuring THz beams.
Measuring Laser Power Below the Noise Floor with a Lock-In Amplifier
Measuring optical signals in the femtowatt (10-15) to nanowatt (10-9) range can be very challenging. This video explains how Lock-In Amplifiers can help make these measurements possible.
Measure Very Low powers Over a Very Broad Spectrum with the RM9 Radiometer
The RM9 system measures powers down to 100 nW over a very broad spectral range, from UV to far IR. This video introduces you to the RM9, and shows you how to use it.
