Electro-Optical Products Corp.Electro-Optical Products Corp. has developed the Variable Low Frequency Modulator/Beam Deflector/Shutter (CH-40) for chopping, deflecting and positioning large, clear aperture laser beams. The chopping vane is mounted on a motor with a limited rotation angle, and the position of the rotor follows the input current with respect to amplitude and frequency. The CH-40 is used when frequencies from DC to 30 Hz are desired. It can hold large vanes, mirrors, gratings and other electro-optical devices.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 6/15/2022Three-Axes Positioning StageThe YPR-45-15-60 series of three-axes positioning stages from Optimal Engineering Systems Inc. features four motor options.
