High Performance Optical Mounts

Optical mounts frequently play a critical role in overall laser system performance. Yet their impact often becomes obvious only when system operation degrades due to optical misalignment induced by vibration, thermal drift or long term mechanical creep in mounts. This article reviews basic styles of optical mount...

What is Measurement Risk?

Do you think your measurement is "In-Tolerance" if the measured value is within the manufacturer's accuracy specification? If the calibration provider is not considering the test uncertainty ratio, chances are your measurements are not what you think they are and it is very likely that you may be making bad...

Six Axes of Calibration

In a system or on a lab bench, proper instrument calibration reduces the chances of false test results. Not all calibrations are equal, and six key factors affect quality, usefulness and cost. In Six Axes of Calibration, we highlight the importance and value of each factor. Download application note.
