Warsash Scientific have announced the release of the new Ophir-Spiricon YAG Focal Spot Analyser, the real-time system for measuring focus spot characteristics of high power lasers.
The Focal Spot Analyser is a compact, laser beam sampler/attenuator for camera-based laser beam profiling systems. Designed for material processing applications such as drilling, ablating, and marking – the focal spot analyser attenuates high power, 1064nm YAG lasers with short, compact path lengths, from 50 to 200mm.
The Focal Spot Analyser supports powers levels from <1 to 400W and focal spot sizes as small as 25μm. Adjustable attenuation up to 1 x 10^-10 maximises the dynamic range of the system.
The system measures focal spot characteristics as well as how focal distance shifts with power. A modular, C-mount unit, the focal spot analyser can easily be added to virtually any CCD camera.
The Ophir-Spiricon patented process provides higher beam width measurement accuracy by determining the background and preserving both positive and negative signals.
