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 Spectra November 2022 IssueMicro-LED DevicesMICLEDI Microdisplays BV has announced microLED devices with integrated micro-lenses for pixel level beam shaping, manufactured in a 300-mm manufacturing flow.
