TP9-BL

Temperature-controlled pyroelectric detector for laser power measurement up to 0.5 mW.

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
