Near Infra-Red (NIR) 2D Birefringence Measurement System

PA/WPA-NIR Series

PA-300-NIR

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.

Case study measuring chalcogenide lenses

Chalcogenide lenses(Visible light is not transmitted and appears black).

Distortion in the lens could be measured as phase difference.

Case study of measuring a cover for LiDAR laser scanner

Cover for LiDAR laser scanner

Weld lines that occur at the confluence of resin in injection molding were measured.

Real-time view also allows you to check the distribution of strain inside the resin while moving the part.
