Abstract
The hazard level of laser products to human eyes mainly depends on the physical parameters of the laser light source,the spectral absorption characteristics of human eye tissue,and the environment in which the products are used.Specifically,it includes the working wavelength of laser light source,luminous mode,emission power or emitted energy,beam divergence angle,angular subtense of apparent source to human eyes and luminous duration,etc.,and at the same time the product use environment,such as the observation distance of human eyes,the size of the spot at the observation distance and the size of the laser power or energy received at the observation distance,etc.will cause different degrees of radiation hazards to human eyes.This paper selects a medical endoscopic laser cold light source with a working wavelength of 785 nm on the market,and then builds the corresponding optical path according to the evaluation method of the extended light source specified in the standard,and detects the opposite angle and achievable emission value of the medical endoscopic laser cold light source,so as to realize the safety classification and hazard assessment of the medical endoscope laser cold light source.关键词
