Medical Endoscope Cold Light Source Testing
The medical endoscope cold light source test solution is developed per YY 1081-2011 Medical Endoscope Cold Light Source standard. It measures relative spectral power distribution P(λ), chromaticity coordinates, CCT, CRI Ra and Ri, peak wavelength, FWHM, luminous flux, radiant flux, red/green/blue flux ratios φer/φeg and φeb/φeg, infrared cutoff φe/φ(300–1700 nm) and all YY 1081-2011 specified parameters for cold light source photometric and colorimetric measurement at the reference window.
