Request InfoFilmetrics, KLA InstrumentsFilmetrics Inc. has introduced two systems for nondestructive measurement of samples on curved surfaces. The products measure two-layer structures and optical constants. The F20-CP is designed to measure translucent or clear reflective coatings and curved surfaces of film up to 50 µm thick, while the F20-XT, with the CP-NIR contact probe attachment, can measure film up to 100 µm thick. The systems require no sample preparation and can fit on a desktop. They also sample with accuracy to within 1% in less than 1 s and either on- or off-line.See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase January 2023 IssueComplete Optical SolutionsPG&O’s complete turnkey optical solutions include high-precision surface quality on prisms and other optics from 0.059- to 30-in. diameter.
