Coherent LM-3 Laser Power Sensor Description:

Datasheet

This LM-3 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 1168339) and RS232-direct (PN 1363752) models are available.

SMA fiber adapter (PN 1098589) and FC/PC fiber adapter (PN 1098339) accessories are available.

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 3W with beam position measurement.

Key Features:

10 mW to 3W range

19 mm diameter active area

Beam position measurement

Spectrally flat broadband coating

0.25 to 10.6 µm spectral range

Convective air-cooled

Fiber adapters available

ISO 17025 accredited
