  • System for testing light sources
    Patent number: 12540845
    Abstract: An example system includes a first color bandpass filter to receive part of light from a light source and a second color bandpass filter to receive part of the light from the light source. The first color bandpass filter and the second color bandpass filter each has a cutoff wavelength at a band edge. The first color bandpass filter and the second color bandpass filter each has a band edge within a predefined distance of a nominal wavelength of the light source. The first color bandpass filter and the second color bandpass filter is each configured to output filtered light that is based on received parts of the light. One or more processing devices are configured to perform operations that include determining at least first and second values based on the filtered light.
