Application Note

Why Is My Sensor Out of Tolerance?

Regular calibration schedules are important. Coherent verifies the condition of your equipment when it arrives for calibration.

Application Note

Care and Handline of Your Coherent Sensor

This document is designed to help answer your questions about the care and handling of your Coherent sensor.

Application Note

Damage Threshold of kW Thermopile Power Sensors

A thermopile detector absorbs incident laser power and heats up, resulting in a temperature rise. This generates an electrical signal through the thermopile arrays arranged around the detector.

Application Note

Justifying Single Point Calibration

This Application Note describes the process that Coherent uses to justify single point calibration for sensors that typically use a single point calibration.

Application Note

LabMax-Pro PC data collection

How do I save my data and how can I look at the data I have previously saved? This Application Note should provide some insight as to how these functions work, and how they may aid you in the future.

Application Note

LaserCam HR II "Ghosting images"

With the introduction of the LaserCam HR II CCD camera, many improved performances have been realized. Lower overall noise, increased sensor sizing, and extension of the product due to the obsolescence issues of the CMOS predecessor.

Application Note

OEM sensor communication and supply connections

This Application Note describes the OEM connections require for interface.

Application Note

PowerMax-Pro kW Push to Connect Fittings

In 2018 Coherent introduced the use of Push to Connect style fittings on the PowerMax-Pro kW sensor due to industry requests for a more internationally used fitting.

Application Note

Understand a Certificate of Calibration

This Application Note provides information in the various sections of a Certificate of Calibration so you can better understand how a meter or sensor is calibrated by Coherent.

Application Note

What is the accuracy specification for positioning on my LM sensor?

Based on our own experience with these products a resolution of around 0.1 mm seems to be the achievable limit on this position measurement feature.

Application Note

Flow Rates and Fittings for Water-Cooled Sensors

This Application Note describes the sensor flow rates and fitting requirements for various water-cooled sensors from Coherent.

Application Note

PMK+ Coating Details for Power Measurement

Coherent has designed a new ceramic absorber coating optimized for best heat transfer and high temperature handling on copper heatsinks.
