The SR-3AR Spectroradiometer is the first instrument in Topcon’s line of spectroradiometers. The SR-3AR provides increased color accuracy (±0.002 xy) and guaranteed accuracy luminance measurements down to 0.1 cd/m2
The four standard apertures (2° / 1° / 0.2° / 0.1°) are automatically selectable by the control panel or through the USB / RS-232 remote interfaces allowing you to optimize the measurement spot size (also a function of working distance) and the minimum measurable luminance level (larger apertures can measure lower levels).
Measure low luminance with accuracy
Measures luminance and color as low as 0.1 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
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

For increased luminance sensitivity, faster measurements, and equal color accuracy, consider the Topcon SR-UL1R, and SR-UL2 Spectroradiometers. These ultra-sensitive instruments provide greater sensitivity for measuring low luminance levels with full spectral analysis. The SR-UL1R and SR-UL2 offer guaranteed luminances of 0.001 and 0.0005 cd/m2 respectively.
