TOPCON Spectroradiometer SR-3AR
일반 용도의 분광방사휘도계(0.1 cd/m2 ~ )
USB2.0 및 RS-232C 통신 지원 - 시스템 개발 용이
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 flicker light source.
Communication between the SR-3AR and PC is accelerated with USB and STB command.
Application soft CS-900A is standard accessories.
