It is suitable for quality evaluation of lenses for VR. MORE WPA-200Series WPA series that expands the measurement range of phase difference from 0 to 3,500 nm by measuring the distribution of birefringence/phase difference over three waves. Suitable for measurement of films and transparent resin products. MORE PA/WPA-NIR Series By using the near-infrared band for the measurement wavelength, this system can measure birefringence/phase difference distribution even for materials that are opaque to the naked eye. Suitable for measurement targets that transmit near-infrared wavelengths, like chalcogenide lenses, LiDAR automotive components, etc. MORE PA-300Series PA series measures birefringence and phase difference with high resolution of 5 million pixels at high speed, for low phase difference with a measurement range of 0 to 130 nm. Suitable for measurement of glassware and other low phase difference targets.
