WPA-200-NIR
PA-300-NIR uses 850 nm in the near-infrared band for the measurement of wave length, the distribution of birefringence/phase difference can be measured at high speed with 5 Megapixels resolution even for materials that are opaque to the naked eye. This equipment is targeted for low phases with a measurement range of 0 to 213 nm.
Suitable for measuring targets that make near-infrared wave lengths transparent like chalcogenide lenses.
WPA-200-NIR uses three wavelengths in the near-infrared band for the measurement wavelengths, and the birefringence of the measurement target transmitting near-infrared wavelengths can be measured.
Suitable for measuring targets that make near-infrared wave lengths transparent like LiDAR automotive components, etc.
