Topcon SR-5 Series
High Dynamic Range Spectroradiometer
The SR-5 is the latest and greatest model available in Topcon’s SR Series line of spectroradiometers (including the SR-3AR, SR-UL1R, SR-UL2, and the SR-LEDH). The SR-5 Series is available in three models including the SR-5, SR-5A, or the SR-5AS. The SR-5 Series is capable of measuring high dynamic ranges from an ultra-low luminance of 0.0001 cd/m² up to an ultra-high luminance of 500,000,000 cd/m² for its top-end model SR-5AS.
Features
Measure high dynamic range with accuracy
Measures luminance and color as low as 0.0001 cd/m2 and as high as 500,000,000 cd/m2 with high accuracy
Luminance, spectral distribution, and CCT measurements
Supports Luminance, Spectral Distribution, CIE1931 and CIE1976 chromaticity coordinates, Tristimulus value XYZ, CCT and Deviation, CIE1976 L*a*b*, Eab*± , CIE1976L*u*v* Euv*±
Four apertures available
Four (4) apertures 0.1°/0.2°/1°/2° enable you to measure luminance from small to wide area without attachment lens
Applications
Luminance, Chromaticity, and Color Temperature measurement of LCDs, CRTs, OLEDs, LEDs, etc
Transmittance of LCD polarizing plates & filters
Luminance and color measurement of various light sources
