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.

PA-300-MT

High-speed, high-resolution measurement of birefringence/retardation targeting the low measurement range (0～130nm), for example glass, optical lens, etc.Separable light source which can be incorporated into inline and measurement stage.

WPA-KAMAKIRI

This product is very effective if evaluation with high spatial resolution is essential.With the WPA series, it is possible to measure a phase difference of about 3000 nm by selecting three different wave lengths and comparing and calculating the phase difference at each wave length.

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.
