Low power thermopile for measuring pulsed & CW lasers between 0.5 mW and 2W.

Key Features:

·      500 µW to 2W range

·      19 mm diameter active area

·      Spectrally flat broadband coating

·      0.19 to 11 µm spectral range

·      Convective air-cooled

·      ISO 17025 accredited

This PM3 sensor is an amplified thermopile power sensor intended for measuring low power lasers down into the mW range.

The sensor is terminated in a SmartSensor DB25 cable and is directly compatible with all power meters in the catalog. A USB-direct model (PN 1174263) is available.

For enhanced thermal stability, the PM3Q (PN 1098419) includes a quartz window to more effectively eliminate thermal background radiation. Note that the window limits the spectral range to 0.3 to 2.1 µm.
