Overview
The SR-LED achieves high cost performance and is specialized in dynamic range up to 4,500,000cd/m².
The SR-LED provides not only luminance and chromaticity data but also Color rendering index and Color temperature date with high speed and high accuracy.
The SR-LED is suited for use in design, developing, and quality control of LED chip and LED module.
Usage
- Luminance, Chromaticity, Color rendering index and Color temperature for LED Back light, LED illuminator.
- Luminance and Chromaticity of TV, PC, Navigation display, Mobile phone display.
- Illumination such as Head light and interior panel of automobile.
- Emergency light and Road light.
Feature
- Measuring wide-dynamic range (1 - 4,500,000 cd/m²)
- Reducing measurement time with HIGH SPEED mode (two times faster than NORMAL mode).
- With Illuminance adapter (option), the illuminance can be measured in addition to Luminance, Chromaticity, Color rendering index and Color temperature.
