Datasheet
This PS19 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.
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 1174261) is available.
For enhanced thermal stability, the PS19Q (PN 1098341) 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 100 μW and 1W.
Key Features:
100 μW to 1W range
19 mm diameter active area
Spectrally flat broadband coating
0.19 to 11 μm spectral range
Convective air-cooled
ISO 17025 accredited
