摘要: The present invention pretains to a device for protecting the human eye by means of a narrow bandwith interference filter which filters out one or more specific wavelengths of light emitted in the form of a coherent, concentrated beam that is laser radiation and in coherent light, an image intensifier for amplifying an image passing through the narrow bandwidth filter to an observable light level, and a neutral density filter which reduces image reflected illuminance to avoid detection.
