Spectroradiometer SR-UL2
Features
-
Ultra-low luminance measurement. (0.0005 cd/m² - )
-
High sensitivity and wide dynamic range (0.0005 - 300,000cd/m²)
-
Luminance and chromaticity in small area can be measured without attachment lens.
-
The stable measured value are obtained even when measuring flicker light source.
-
Communication between the SR-UL2 and PC is accelerated with USB and STB command.
-
Application soft CS-900A is standard accessories.
