Topcon SR-NIR Near Infrared Spectroradiometer

Topcon SR-NIR
Near Infrared Spectroradiometer

The SR-NIR Spectroradiometer can measure spectral distribution in the near infrared range (600nm – 1030nm). The four standard apertures (2° / 1° / 0.2° / 0.1°) are automatically selectable by the control panel or through the USB / RS-232 remote interfaces allowing you to optimize the measurement spot size (also a function of working distance) and the minimum measurable luminance level (larger apertures can measure lower levels).
