Medical Endoscope Cold Light Source Testing
Medical endoscope cold light sources are tested per YY 1081-2011 at the reference window for Ra, CCT, flux ratios and IR cutoff. SPM-8000Y with fibre and sphere covers colorimetry; IUT-500/PH-200 handles illuminance uniformity.
Definition & Scope
Medical endoscope cold light sources supply illumination for endoscopic imaging; their photometric and colorimetric performance affects clinical image quality and safety. YY 1081-2011 specifies parameters at the reference window: P(λ), chromaticity, CCT Tc, CRI Ra/Ri, peak wavelength and FWHM, luminous/radiant flux, red/green/blue flux ratios, IR cutoff φe/φ(300–1700 nm), plus illuminance uniformity and exceedance points. Spectral colorimetry typically uses SPM-8000Y with a BaSO4 integrating sphere; uniformity testing uses the IUT-500 medical cold light uniformity system centred on the PH-200 photometer with dedicated fixtures and software for uniformity, exceedance count, average illuminance and relative sample standard deviation.
