Introduce
- SR-5AS is a new generation spectroradiometer that can measure from ultra-low luminance to ultra-high luminance with high sensitivity and high speed.
Feature
- High dynamic range measuring(0.0001 – 500,000,000cd/m²)
- Reduction of measurement speed. It can measure more speedy using High speed mode.
- Significant improvement in usability by adopting a color touch panel.
- Pursuit of the best function and compatibility for measurement system installation.
- High accuracy measurement of flashing light (Synchronous measurement function / Integral time delay function).
- Standard accessory software can control SR-5AS and can process measured data with simple operation.
Application
- Luminance, Chromaticity, Color rendering index and Color temperature for LED Back light, LED lighting.
- Luminance and Chromaticity of µLED/Mini LED、OLED、LCD, Tablet, Smart phone display.
- Luminance and Chromaticity of head light and interior panel of automobile.
- Used as optical characteristic evaluation sensor for system equipment.
- Production line(high precision gamma measurement with spectral measuring),R&D(various evaluation such as IVL-measuring).
- Used as optical characteristic evaluation sensor for system equipment.).
