Request InfoEngis UK Ltd.HENLEY-on-THAMES, England, Jan. 14, 2013 — Engis UK Ltd. has launched its newly engineered nonagglomerating diamond slurry, designed for pitch polishing applications, including lapping and polishing of precision optical materials and components such as proof flats, etalons, prisms, windows and ring laser gyroscope blanks. Pitch transfers minimum load to the polishing media, resulting in subnanometer surface roughness that is not obtainable through other polishing techniques. The benefits of the Hyprez pitch polishing slurry include fast cutting and polishing rates, a wide range of diamond particle sizes and minimal waste...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2023 IssueAutomated Resist Processing SystemThe 200-mm version of the EVG®150 automated resist processing system from the EV Group is an optical lithography platform that includes advanced features and enhancements that provide even...Vision Spectra Autumn 2022 IssueMachine Vision CamerasJAI AS has expanded its Go-X series of small machine vision cameras to include 24 new global shutter camera models with the latest Sony Pregius S CMOS sensors.
