100 nW to 100 mW Pyroelectric 0.1-30 THz Radiometer System
100 nW to 100 mW Pyroelectric 0.1-30 THz Radiometer System
The RM9-THz with Chopper radiometer system is a sensor and optical beam chopper combination for measuring the power of very low level CW or quasi CW light sources. This sensor was specially designed for work in the terahertz range. The RM9-THz sensor has a pyroelectric element to measure a wide dynamic range of radiation, from 100 nW to 100 mW. It has an 8 mm aperture and covers the spectral range from 0.1 to 30THz. The system comes with the RMC1 chopper that is placed between the source and the RM9 sensor.
- Pyroelectric sensor with 0.1 to 30 THz spectral range
- 100 nW to 100 mW power measurement range
- 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.
