Coherent LM-2500 Laser Power Sensor Description：

Datasheet

This BeamFinder sensor is terminated in a SmartSensor DB25 cable and is directly compatible with LabMax-TOP, LabMax-TO and LabMax-Pro SSIM meters. A Thermal SmartSensor Adapter PN 1056827 is required to use this sensor with FieldMate, FieldMaxII-TOP and FieldMaxII-TO meters.

These unique position sensing thermopiles display the position of the incident beam on the sensor disk, in addition to measuring power when used with the LabMax and LabMax-Pro meters. 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 2500W with beam position measurement.
