It can be frustrating – trying to measure the power of a laser beam whose power keeps changing. In this video, part of our “Best Practices in Laser Measurement” series, you’ll learn how to get good readings even for unstable beams.
When measuring very high power laser beams, even the few percent of the beam normally back-scattered from the sensor can be a problem. Ophir now offers Scatter Shields as accessories for our high power laser sensors; these can be mounted on the front flange of the sensors to reduce the backscatter by about 70%.
What are the four things you need to know when selecting a laser beam profiling system? Learn from Ophir-Spiricon’s sales engineers – the experts in the field of measuring lasers – what you need to know to get the most out of your laser beam.
Modern production facilities must constantly increase throughput, at less cost, with less scrap, and with minimum downtime. In this video overview, you will learn how application of new, advanced technology in measurement devices, can help both designers and users of industrial laser systems to optimize and control their processes, so they can accomplish these goals and achieve consistently good results – both in quality and quantity.
Measuring the focal spot of a high power laser is challenging, at best.
The main issue is that when a high power laser is focused down to a small point, the power density can be extremely high, typically high enough to damage any sort of measurement equipment you would use.
Does power density damage threshold really change with power? Shouldn’t it remain the same throughout the whole power range? In this video you’ll learn why the specified damage threshold does indeed depend on the power level, and not just on power density.
BeamMaker helps engineers, technicians, and researchers understand a beam’s modal content by creating a theoretically generated beam. Design your perfect beam profile in BeamMaker by specifying the mode, size, width, height, intensity, angle, and noise content – then configure your laser to run as designed, and compare your actual beam to the theoretically derived measurements. The end result is knowledge about how much the real beam varies from the desired beam.
In applications where a human observer is involved (for example illumination applications), it is often important to measure using the eye-response-matched Photometric system of units. Ophir’s PD300-CIE is a photometric sensor, and is designed to measure illuminance (in units of Lux or Foot-Candles).
