Paper Abstract

Recent consumer awareness of previously unquestioned devices, tne misuse of products and developments in optical technology have created a demand for a better understanding of the potentially adverse effects from intense optical sources. The commercial application of lasers and the various standards for laser product performance have also accelerated this demand for an understanding of the effects of broad band optical sources. The potential for adverse eye changes while viewing the sun during solar eclipse has been recorded since early timer and the reddening of skin and sunburn have been experienced by most people. The Biomedical studies to quantify the effects of spectral emission and dose relationship from manmade sources has recently been undertaken. It is only within the last several decades that the need for understanding the biological effects of optical radiation upon man has become of interest. Much of the early work in understanding these effects resulted from interest in therapeutic application. It is only within the last decade that research has considered the non-therapeutic effects. To our knowledge only a few organizations have thus far established exposure criteria from broad band optical sources to prevent the harmful effects of overexposure. This paper will detail the techniques used by the Xerox Corporation to evaluate broad band optical sources for use in office machines. While the specific examples will be for fluorescent lamp sources, the limits and procedures are equally valid for other broad band optical sources such as arc, flash and lamp arrays found in most industrial, commercial and military applications.
