Coherent LM-45 Laser Power Sensor Description:

Datasheet User's Manual

This LM-45 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.

USB-direct (PN 1168342) and RS232-direct (PN 1211474) models are available.

SMA fiber adapter (PN 1098589) and FC/PC fiber adapter (PN 1098339) accessories are available when used with 1.035-40M Adapter Ring (PN 33-9432-000).

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.

Convectively cooled thermopile for measuring pulsed & CW lasers up to 25W with beam position measurement.
