Coherent PowerMax-RS LM-5000 Laser Power Sensor Description：

Datasheet

This PowerMax-RS LM-5000 sensor is terminated in an RS232 cable that interfaces directly to a PC or industrial controller. A DB25 model (PN 1098421) is available.

These unique position sensing thermopiles display the position of the incident beam on the sensor disk, in addition to measuring power. This information allows the user to safely and precisely align the sensor and the beam being measured. This is particularly useful for non-visible beams.

Water-cooled thermopile for measuring lasers up to 5000W with beam position measurement. Direct RS232 interface.
