Datasheet
This PM3Q sensor is an amplified thermopile power sensor intended for measuring low power lasers down into the mW range. It includes a quartz window to more effectively eliminate thermal background radiation. Note that the window limits the spectral range to 0.3 to 2 μm.
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 1191133) is available.
For a wider spectral range, the similar PM3 model (PN 1098336) does not include the quartz filter, enabling a spectral range of 0.19 to 11 μm.
