Ophir Photonics has launched the newest version of the M2-200s, the company's camera-based beam propagation analyser. The M2-200s is an ISO 11146-compliant system that automatically measures laser beam quality in less than two minutes and features a robust design that supports continuous operation. The latest version enhances the system's robust packaging with a new motor controller that decreases noise from motor movement by 30 per cent.
The M2-200s is a compact, portable unit that features a CCD camera for use with pulsed or CW lasers, 266-1,300nm. The 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, 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.
