Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsPhysik Instrumente has introduced the S-340 Piezoelectric Tip/Tilt Platform for fast laser beam steering and image stabilization. The platform accommodates mirrors and optics with diameters up to 3 in. and can be operated in step or continuous modes. PI says the two piezo actuators and two linear variable differentiation transformer displacement sensors per axis guarantee maximum temperature stability and a <1 µrad resolution. Applications include boresight systems and active optics.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/31/2023XYZ PlatformThe H189 XYZ high-precision motorized XYZ deck from Prior Scientific Inc. is a versatile platform designed to complement the latest generation of 2P/3P/multiphoton/confocal microscopy systems. ...Photonics.com 6/19/2023Lidar Testing SystemThe E8717A Lidar Target Simulator (LTS) from Keysight Technologies Inc. is a compact, automated benchtop solution that allows automakers and sensor manufacturers to test and validate autonomous...Photonics.com 9/2/2022Fiber Laser LidarThe 1550-nm LS series of automotive-grade fiber laser lidar from LeiShen Intelligent System Co.
