Request InfoThorlabs Inc.Thorlabs Inc. has introduced the BP1M2 series, an extension set for the BP100 series beam profiler that enables automated measurement of the M2 factor, a more accurate expression of beam quality than a single profile measurement. The set comprises a motor translation stage and mounting accessories. Stage movement is controlled by the beam profiler software, allowing measurement of the beam diameter at various positions along the propagation axis. A hyperbolic curve fit to the data yields values for the beam waist, diameter and position, as well as the Rayleigh range, divergence angle, beam...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 6/26/2023Beam ProfilerThe high-power NFScan diverging beam profiler from Photonics Automation outputs up to 500 W for real-time beam profiling for diverging sources sized <1 mm, such as fiber coupled lasers; single...Photonics.com 6/13/2023Linear Voice Coil MotorThe HVCM-051-032-013-01 Linear Voice Coil Motor from Moticont features a high force-to-size ratio and a 19.1-mm stroke.
