GL Spectrosoft Light Measurement Software Supports the New Color Fidelity Index Rf
GL Optic has upgraded its software GL Spectrosoft Pro to meet the latest requirements of the international CIE (International Commission on Illumination). The number of reference colors used to calculate the Ra value has been increased from 8 to 99 reference colors to calculate the new Rf value.…
At the end of April 2017, the CIE (International Commission on Illumination) published a new standard – CIE 224:2017 Color Fidelity Index – for accurate scientific use on a new color fidelity index called Rf. This index takes into account the spectral characteristics of white LED light sources. To develop the new methodology, thousands of different LED sources and luminaires were analyzed and the number of reference colors used to calculate the Ra value was increased from 8 to 99 colors to calculate the new Rf value. The new index was introduced as a supplement to the Ra value for scientific purposes. All professionals in the lighting industry and discerning customers can now compare and select LED products more objectively in terms of color rendering quality.
GL spectrometers are used to measure any light sources. With the new software GL Spectrosoft Pro, the measured values can be analyzed and the new Color Fidelity Index can be determined.
