Request InfoOptical Perspectives Group LLCOptical Perspectives Group LLC has developed the CaliBall to calibrate phase-measuring interferometers. The 25.4-mm-diameter silicon nitride ball and its kinematic mount determine the errors in the transmission-sphere reference surface. The device is located with its center at the focus of the interferometer transmission sphere and aligned to better than one fringe. For calibration, a measurement is taken, and the ball is picked up, arbitrarily rotated and replaced in its mount. The center of the ball returns to its original position as a result of the kinematic mount. The process is repeated...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/27/2024Small Beamsplitter DetectorThe LIM-082 from InfraTec is a small beamsplitter detector in current mode that can be used in gas measurement technology.
