Coherent PowerMax-USB PM3 Low Power Sensor Description：

User's Manual

This PowerMax-USB 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 USB cable that interfaces directly to a PC. A DB25 model (PN 1098336) is available.

For enhanced thermal stability, the PowerMax-USB PM3Q (PN 1191133) 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.

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

Key Features:

500 µW to 2W range

19 mm diameter active area

Spectrally flat broadband coating
