Spectrophotometric Hazemeter

The HSP-150Vis and HSP-150VIR, with spectroscopic capability, are designed to measure transmittance and haze value per wavelength as well as the color value and yellowness. The haze meters are set up in a vertical configuration, allowing the user to easily measure a wide range of the sample shapes and sizes.


Highly functional film related to solar cells, automobiles, building materials, touch panels and LED. Assessment of Haze on Glass with wavelength dependence.
