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.
