Product Details

TOPCON Ultra Low Brightness Spectroradiometer

SR-UL1R ultra-low brightness spectrophotometer

SR-UL1R ultra-low brightness spectrophotometeryesThe upgraded version of the original model SR-UL1 has sensitivity based on the SR-UL1Improved to some extent.

This greatly improves the operability of the product. In addition, when using a 2 ° measurement angle, the ultra-low brightness of 0.001cd/m2 can ensure its measurement accuracy.

feature

Ultra low brightness instrument, capable of measuring 0.001 cd/m ².

Wide range, with a range of 0.001-300000 cd/m ².

Without the need for auxiliary mirrors, it can accurately measure low brightness areas of fine surfaces.

High precision measurement of strobe light source (equipped with synchronous measurement function and integration time delay function)

Using standard application software, it can perform rich data processing and host control.

main purpose

Brightness, chromaticity, color temperature characteristics, contrast measurement, light distribution characteristics, and all optical characteristic evaluation indicators for displays, lighting, etc

High precision measurement of brightness and chromaticity of fine surfaces such as automotive instrument panels, audio systems, and control panels

Evaluation of Light Quality for Other, Traffic Signs, Signal Lights, and Various Special Light Sources
