High Fidelity And Full Color Gamut

TM-30-15 is a new method for measuring color rendition, trying to supplant CRI. It comprises three primary components:

  • 1. Rf- a fidelity index that is similar to the commonly used CRI
  • 2. Rg- a gamut index that provides information about saturation
  • 3. Color vector graphic- a graphical representation of hue and saturation relative to a reference source

There are two main differences between TM-30-15 and CRI. One is that CRI provides information about fidelity, but does not provide any information on saturation while TM-30-15 uses the Gamut Index (Rg) to describe differences in saturation. The other is that whereas CRI uses only eight color samples to determine fidelity, the TM-30-15 uses 99 color samples. Such an artificially high CRI value would result in a lower TM-30-15 value since TM-30-15 has 99 color samples. After all, matching spectrum peaks to 99 color samples is very difficult.

After several years of phosphor recipe development, we achieved to have high Rf scores and could design SPDs based on fundamental black body curves.
