Surface Characterization and Stress Analysis
VNIR polarization hyperspectral imaging provides multidimensional insights
Unlike conventional polarization cameras that only capture polarization states, the VNIR Polarization Hyperspectral Camera simultaneously combines spectral and polarization data across the 400–1000 nm range with 1 nm sampling intervals, delivering richer material surface information. With complete Stokes parameter output, it enables surface roughness analysis, stress distribution detection, and material identification across a wide range of industrial inspection applications.
Surface roughness is a key indicator of product quality and functionality. The VNIR Polarization Hyperspectral Camera simultaneously captures spectral reflectance and polarization information, accurately revealing fine surface textures and relief structures. It is widely applicable to surface quality inspection in consumer electronics, precision components, and more.

Residual stress in plastic molding is often invisible to the naked eye, yet it can significantly affect structural integrity and product lifespan. By analyzing the Angle of Polarization (AOP) and Degree of Polarization (DOP), the VNIR Polarization Hyperspectral Camera enables non-contact visualization of internal stress distribution, helping manufacturers detect potential defects early and improve product reliability.
