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.
