BeamSquared

MKS Instruments announced BeamSquared, a new M2 laser beam propagation system from Ophir that measures the quality of the beam to optimize performance. BeamSquared is a compact, portable device that provides automated measurements of the propagation characteristics of CW and pulsed lasers in under one minute. It is durable and operationally robust, ensuring reliable, high accuracy measurements of lasers. Users can run the system in automated mode from UV to NIR, and telecom wavelengths, and in manual mode for terahertz and CO2 laser beams.

BeamSquared is designed for continuous use applications, from scientific research to rapid prototyping to fabrication and machining. The system includes the BeamSquared M2 software; a high accuracy CCD, InGaAs, or pyroelectric array camera; and an optical train. The software measures beam propagation characteristics on both the X and Y axes, including waist diameters, full angle divergences, waist locations, Rayleigh lengths, M2 or K and BPP factors, astigmatism, and asymmetry. 2D or 3D beam profiles can also be displayed for visual verification of beam profile behavior through focus.

Gary Wagner, General Manager, Ophir (U.S.) said, "BeamSquared quickly and accurately measures laser quality, helping users get the best performance possible. The system combines a longer optical train with our patented Ultracal™ calibration algorithm to deliver highly accurate measurements and full ISO 11146 compliance. The system is fast, producing a full array of beam measurements in less than one minute. Plus it's robust, able to run continuously, three shifts a day, seven days a week."

BeamSquared is a camera-based laser measurement system. Users choose the appropriate camera for their application:

+ Ophir's SP300 silicon CCD camera accurately captures and analyzes wavelengths from 190nm - 1100nm. It features a compact design, wide dynamic range, unparalleled signal to noise ratio, and reduced blooming.

+ Ophir's Xeva XC-130 high resolution InGaAs camera accurately captures and analyzes wavelengths from 900nm - 1700nm. It features operation at room temperature, a wide dynamic range, a fast data capture rate, and a large array that makes it ideal for large beam NIR laser and telecom mode field analysis.

+ Ophir's Pyrocam pyroelectric array camera accurately captures and analyzes wavelengths from 1.06?m - >3000?m. Available in two versions: Pyrocam IVs, a 25.6 X 25.6mm active array and Pyrocam IIIHR, a smaller-format OEM version with a 12.8 X 12.8mm array.
