Low Noise Lock In Power Sensors
The RM9 series Radiometers use a pyroelectric or photodiode sensor in conjunction with chopped CW or quasi CW radiation, using a digitally synthesized lock-in amplifier to reduce external noise to a minimum.
RM9 with Chopper 100 nW to 100 mW Pyroelectric Radiometer System
- Pyroelectric sensor with 0.15-12 µm spectral range
- 100 nW to 100 mW power measurement range
- Chopper and lock in amplifier for lowest noise and drift
RM9-PD with Chopper 300 fW to 300 nW Photodiode Radiometer System
- Photodiode sensor with 200-1100 nm spectral range
- 300 fW to 300 nW power measurement range
- Chopper and lock in amplifier for lowest noise and drift
RM9-Pyro 100 nW to 100 mW Pyroelectric Radiometer
- 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
RM9-PD 300 fW to 300 nW Photodiode Radiometer
- Photodiode sensor with 200-1100 nm spectral range
- 300 fW to 300 nW power measurement range
- Use RMC1 or other chopper and lock in amplifier for lowest noise and drift
