Evaluation of Laser Eye Protetors Commercially Available.
Abstract
The transmission characteristics of commercially available laser eye protectors were measured with a Cary 14 spectrophotometer, to determine the conformance of each to the respective manufacturer's specifications. The luminous transmission of each eye protector was calculated relative to a 5750 K blackbody source of illumination (an approximation of the sea-level illumination of sunlight), and generally proved to be consistent with that advertised by the respective manufacturer. These measurements were also used to determine qualitatively the protection wavelength region for each device. Each of the eye protectors was exposed directly to high-intensity radiation from the lasers in order to measure the high optical density (OD) inherent in most of these devices and to confirm that the specified OD was always maintained. The following types of lasers were used for these tests--a normal pulse neodymium, a Q-switch ruby, a normal pulse ruby, and a continuous-wave helium-neon. Also outlined in this report are some guidelines for the design, selection, and use of eye protectors. (Author)
