{"id":1616,"count":4,"description":"The <strong class=\"d2b1\">PhaseCam\u00ae<\/strong> range of instruments is based on the <strong class=\"d2b1\">Twyman-Green interferometer<\/strong> principle. Thanks to its polarized pixel camera (patented by <strong class=\"d2b1\">4D Technology<\/strong>), the <strong class=\"d2b1\">PhaseCam\u00ae<\/strong> can acquire data in a single phase, making it the first truly <strong class=\"d2b1\">vibration-insensitive interferometer<\/strong>. It is particularly well suited to testing large mirrors, where vibration isolation is often a problem.\r\n\r\nWhat's more, turbulence or long optical paths do not affect its measurement accuracy. It can also be used to measure moving or deformable optical surfaces.\r\n\r\nWavefront acquisition takes place in tens or hundreds of microseconds, thanks to 4D Technology's patented spatial phase-shifting technique.\r\n\r\nAs an option, the <strong class=\"d2b1\">PhaseCam\u00ae interferometer<\/strong> can be configured for use in vacuum.\r\n\r\nThe latest-generation <strong class=\"d2b1\">4Sight\u2122 Focus Analysis software<\/strong> is used to control instrument parameters, perform data acquisition, create complex masks, generate reference files, calculate Zernike and Seidel coefficients...\r\n\r\nThe <strong class=\"d2b1\">PhaseCam\u00ae interferometer<\/strong> is now considered the benchmark for dynamic interferometry in the <strong class=\"d2b1\">high-precision optics sector<\/strong>. It is available in several standard versions, and can be customized to meet your specific requirements.\r\n\r\nNumerous accessories and options are available, including a 5-axis mount, low-reflectivity divergent lenses and beam expanders. An external high-power 532nm source for ESPI (Electronic Speckle Pattern Interferometry) is also available.\r\n<h2 class=\"h5\">Discover the different versions of our PhaseCam\u00ae interferometer range:<\/h2>","link":"https:\/\/www.trioptics.fr\/en\/product-category\/optical-metrology-equipment\/4d-technology-interferometers\/phasecam-twyman-green-interferometers-phasecam\/","name":"Twyman-Green interferometers: PhaseCam","slug":"phasecam-twyman-green-interferometers-phasecam","taxonomy":"product_cat","parent":1615,"meta":[],"menu_order":81,"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Twyman-Green interferometers, high-precision optical inspection PhaseCam<\/title>\n<meta name=\"description\" content=\"Trioptics offers a wide range of optical topography measurement instruments, such as the Twyman-Green interferometer.
