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.
