TP9-BL
Temperature-controlled pyroelectric detector for laser power measurement from nW to 0.5 mW.
Product family key features
Spectrally flat response
These radiometers were developed for NIST, to be used with a broadband spectrometer to act as a spectral transfer standard when calibrating other detectors in the 0.25 to 15 μm range.
Temperature Controlled Power Measurement
Each head is composed of a low noise detector, thermistor, TE cooler and heatsink to compensate for any temperature change
The Ultimate Choice in Measurement Stability
Temperature control down to 0.05°C from 20 to 30°C gives a temperature coefficient <0.01 %, thus a voltage output stable to 0.01 %
2 Sizes Available
- TP5-BL: 5 mm Ø pyroelectric sensor with organic black coating
- TP9-BL: 9 mm Ø pyroelectric sensor with organic black coating
To be used with the STEP-Controller
Plug your TP sensor into the STEP-Controller for power supply and temperature control. You can then use the analog output with a scope or lock-in
