Outline

Recently, demands for measuring near-infrared spectral region have increased, however, especially in FPD and lighting market, there is not handy and high accuracy measuring instrument.
Under these circumstances, we have developed NIR Spectroradiometer SR-NIR based on technology of our famous SR-3AR. And, you can measure Spectral radiance from 380nm to 1030nm using by both other SR series and SR-NIR.

Features

Features

  • Measurable ultra weak optical signal of near-infrared spectral region from flat panel display
  • High accuracy measuring of near-infrared spectral region.
  • Measurable near-infrared spectral form 380nm to 1030nm using by both other SR series and SR-NIR.

 

Applications

  • For measuring near infra-infrared spectral region from FPD such as LCD and OLED.
  • For measuring Nr, Ar line spectra
  • For measuring transmission characteristics of film sheet in near-infrared spectral region
  • Nir infra-infrared spectral region from other light source
