3.7.1 Camera Based Beam Propagation Analyzer: M2 3.7.1.1 Automatically measure your beam quality in under 2 minutes Tune your laser for best operation ISO compliant Specifically developed for continuous usage Unequaled accuracy using patented UltracalTM Calibration Automatic attenuation adjustment Pulsed and CW for most beam diameters and powers Compact and portable Not all commercial M2 measuring instruments conform to the ISO 11146 method of employing a fixed position lens and moving detector. Instead, some manufacturers use a fixed position detector and a moving lens. If the laser beam is diverging or converging within the travel range of a moving lens, the reported M2 value and other results can be significantly compromised. Spiricon's M2-200s Beam Propagation Analyzer is fully ISO 11146 compliant. Automatic M2 - at Production Speeds Steering Mirrors Beam Attenuator Beam Attenuater 1st Camera Alignment Tool The M2-200s optical train uses a fixed position lens and camera. The mirrors that direct the focused beam into the camera are moved to precise locations, translating the beam through both the waist region and the far field regions. All these measurements and translations, as well as incremental beam attenuation, are automatically controlled by the M2-200s software. Software improvements in the M2-200s, including more efficient algorithm execution, has decreased the measurement reporting time by 2-3 times, making it possible to report M2 in under two minutes. 219 For latest updates please visit our website: www.ophiropt.com/

Manual mode is available for beams that are too large or too small or at wavelengths outside the standard optical train. Spiricon products are known for accuracy. Using our patented Ultracal™ calibration method and auto aperturing to exclude noise beyond the wings of the laser beam, assures the user of the most accurate measurements in the industry. Spiricon has redesigned the M2-200, the world's top selling beam propagation system to include customer input, increased attention to durability, and operational robustness for continuous use applications - three shifts a day, seven days a week.
