Request InfoPLX Inc.DEER PARK, N.Y., May 19, 2020 — The ACT-25FO autocollimator from PLX Inc. combines the functions of a collimator and telescope to make a high-accuracy measurement instrument capable of resolution down to 0.01 arc-sec. The device has a motorized focusing knob controlled by a supplied software. The focusing function allows focusing on objects along the optical axis of the autocollimator with line of sight deviations of <2.5 s. When used as an autocollimator, the unit has a 25-min. horizontal measurement range. In alignment telescope mode, the field of view is 50 min., horizontally. Its focusing range is from 17.5 cm...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/14/2023Four-axis StagesThe XYZ-Goniometer series of four-axis stages from Optimal Engineering Systems Inc. feature four motor options.
