Spectroradiometer SR-5AS
New SR series
Flagship model
HDR measurement
0.0001cd/m²
Outline
SR-5AS is a new generation spectroradiometer that can measure from ultra-low luminance to ultra-high luminance with high sensitivity and high speed.
Measurement range at measurement angle 2° is ultra-low luminance from 0.0001 cd / m² to expands the range of high luminance to 500,000,000 cd / m².
SR-5AS can measure ultra-high brightness LED without using an external ND filter.
SR-5AS realize reduction of measurement time with renewal the optical system and improvement of internal system algorithm.
Significant improvement in usability by adopting big-size color touch panel.
Features
■ High dynamic range measuring(0.0001 – 500,000,000cd/m²)
■ Reduction of measuement 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.
Principal use
■ 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.).
