Abstract

Projectors of varying technologies have been in use for several decades in home and office environments. These include 35-mm slide projectors, overhead projectors, and more recently digital projectors. The trend in digital projectors has been increasing luminance from smaller products. This has been made possible by the advent of new or improved light sources and projection technologies. Results of a comparative evaluation of ocular hazards from various projection systems, including a mobile laser projection system are presented. Irradiance and source size measurements were made to determine the radiance of each of the projection systems for thermal and blue light hazards. Ultraviolet and infrared measurements were also made for completeness of the hazard evaluation. Projectors are classified by risk groups according to the 1EC 62471, first edition (CIE S009).
