INTERNATIONAL Light has released a portable spectroradiometer, available from Warsash Scientific . It is powered by a USB connection and provides NIST traceable data to yield CRI (colour rendering index) characterisation.
The IL RPS-380 Portable Spectroradiometer is a compact instrument that can perform colour repeatability and brightness sampling within a few seconds for measuring primary radiance and luminance. It is suitable for testing LED display panels, illumination modules, and large signage to check that all colour segments are equal. It provides data to yield CRI characterisation.
It is designed for measurements in the 380nm to 780nm spectral range with 5nm to 10nm resolution. The spectroradiometer uses Windows-compatible software with CIE chromaticity diagrams, dominant wavelength and photoptic weighting calculations. Primary applications include colour calibration, quality assurance and lot to lot testing.
