Request InfoMcPHERSONCHELMSFORD, Mass., Oct. 8, 2015 — Able to function in high and ultrahigh vacuum systems, a line of mechanical positioning systems with high load capacity and stiffness is offered by McPherson Inc. The strut-based mounting system minimizes vibration and allows submillimeter position adjustment of a variety of hardware. The six struts provide seismically adequate support for instruments weighing 200 pounds and more. The strut mechanical positioner has up to six degrees of freedom — translational XYZ motion, as well as angular pitch, roll, and yaw motion. Applications include alignment, mounting and...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/26/2022Optical MountsThe E-Series of Adjustable Size Kinematic Optical Mounts from Edmund Optics Inc. can be used for mounting a wide range of round, rectangular, and square optical components, including round and...Photonics Spectra July 2023 IssueMirror MountsWedged back paraboloid mounts from Optical Surfaces Ltd. provide a secure and stable platform for mirror diameters from 50 to 200 mm.
