Near Infrared Spectroradiometer SR-NIR

High-accuracy measuring with spectrometry for near-infrared region 600-1030nm.

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

￭ 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.

Principal use

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