Spectroradiometer SR-3AR
Remain a long-selling product model as a various industry standard.
Outline
Recently, a quality and functional of display has been increased, the needs for more sophisticated instrument is growing.
This product features highly accurate and high-speed measurement, so it can be used to complete a wide variety of needs.
The SR-3AR replaces SR-3A/SR-3A-L1 with enhancement of measurement range and stability.
Features
￭ High accuracy with spectrophotometry and high-speed measurement.
￭ Luminance and chromaticity in small area can be measured without attachment lens.
￭ Measurement angle are selectable from 2°/ 1°/ 0.2°/ 0.1°)
￭ The stable measured value are obtained even when measuring frequency light source.
￭ Communication between the SR-3AR and PC is accelerated with USB and STB command.
￭ Application soft CS-900A is standard accessories.
Principal use
￭ A various of flat panel display, FPD related materials.
￭ Outdoor billboard, Digital signage.
￭ Automobile instrument panel, audio, lamp, operating panel.
￭ Traffic sign, Traffic light.
￭ Generic illumination, Special illumination.
