Ophir Photonics has introduced the M2-200s, a camera-based beam propagation analyser. The M2-200s is an ISO 11146 compliant system that automatically measures laser beam quality. The latest version adds support for the 64-bit Windows 7, addressing more physical memory, minimising the time required to swap processes, and speeding up the measurement cycle to less than two minutes.
Designed for continuous 24/7 use, the M2-200s features a CCD camera that works with pulsed or CW lasers, 266-1300nm. The compact, portable system automatically measures M2, beam waist location and width, divergence, astigmatism, asymmetry ratio, and the Rayleigh range for each axis. Input beam sizes can range from 0.5-10mm. Manual mode is available for beams that are too large or too small, or for wavelengths outside the standard optical train.
The M2-200s supports both the 64-bit and 32-bit versions of Windows 7, enhancing system configuration options and increasing processing speed. The software displays a 2D or 3D beam profile of the currently measured point in the beam propagation curve. After each run, the beam profile of any individual measured point can be observed. Outlying or anomalous points can be automatically or manually excluded from the curve fit calculations for more accurate results.
The M2-200s software is based on Spiricon's patented UltraCal calibration method and auto aperturing. This excludes noise beyond the wings of the laser beam and assures high accuracy measurements.
