Coherent PowerMax-RS PS19Q Low Power Sensor Description：

Datasheet User's Manual

This PowerMax-RS PS19Q sensor is a thermally stabilized, amplified thermopile power sensor intended for measuring low power lasers down into the 100 μW range, making it ideal for measuring laser diodes, HeNe and ion lasers, and other low power laser sources. It includes a quartz window to more effectively eliminate thermal background radiation. Note that the window limits the spectral range to 0.3 to 2.1 μm.

The sensor is terminated in an RS232 cable that interfaces directly to a PC or industrial controller. DB25 (PN 1098341) and USB direct (PN 1168343) are available.

Low power thermopile for measuring pulsed & CW lasers between 100 μW and 1W. Includes a quartz window to more effectively eliminate thermal background radiation. Direct RS232 interface
