Scope

Scope: This document specifies the requirements and test methods for medical endoscopic cold light sources with near-infrared excitation light. This document applies to cold light sources used as functional supply devices in endoscopic examinations and surgeries. Other cold light sources can be selected based on their applicability. Main technical content: structure, spectral performance (color rendering index, correlated color temperature, radiant flux ratio of red, green, and blue light, spectral characteristics of near-infrared excitation light, infrared cutoff performance), illumination uniformity of reference windows (illumination uniformity, illuminance over-limit point), radiation performance (total output luminous flux), excitation light power, reproducibility of excitation light output power, instability of excitation light output power, electrical safety, mechanical interface specifications, and safety measures against malfunctions.
