Request InfoBristol Instruments Inc.Bristol Instruments offers a family of instruments that use the unique properties of light to precisely measure the critical parameter of thickness. The primary advantage of this optical technique is that it makes non-contact measurements with sub-micron accuracy. Both hard and soft materials are analyzed without damage or deformation. In addition, this optical technique enables the simultaneous measurement of up to 31 layers. Originally designed for R&D and laboratory environments, Bristol Optical Thickness Gauges have evolved into high volume production and in-line quality control...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 1/14/2022Light EngineThe EnLiten30 light engine from DigiLens Inc. is a 30°, 720p landscape field-of-view liquid crystal on silicon LED for near-to-eye optical technology.
