100 nW to 100 mW Pyroelectric Sensor Radiometer
100 nW to 100 mW Pyroelectric Sensor Radiometer
The RM9-Pyro radiometer is a sensor for measuring the power of very low level CW or quasi CW lasers and light sources. The RM9 uses a pyroelectric sensor and lock-in amplifier with an 18 Hz chopper (not included, use RMC1 or other chopper) to measure a wide range of radiation, from <100 nW to 100 mW. It has an 8mm aperture and covers the spectral range from 0.15 to 12 µm.
- Pyroelectric sensor with 0.15-12 µm 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
Software
Full support available for the RM9 sensor with the Centauri, Vega, Nova II, Juno, Juno+, Juno-RS, EA-1, StarLite and StarBright and with the StarLab application.
There is limited support for the RM9 sensor with the older LaserStar, Pulsar, Quasar and Nova.

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.
