INVESTIGATION OF THE EFFECTS OF RUBY LASER RADIATION ON OCULAR TISSUE

Abstract

A series of laboratory and field experiments on rabbits were conducted by the New York Eye and Ear Infirmary in order to establish tentative safe operational distances and conditions for use of the Frankford Arsenal XM23 Laser Rangefinder. The measured far field corneal threshold dose for rabbits was tentatively determined to be 5 x 10 to the minus 7th power joule/sq. cm. From this a possible human corneal threshold was calculated as 0.00000145 joule/ sq. cm. Based on this value, tentative safe operational distances were calculated as being 6460 meters for night (8 mm pupil), 1615 meters for twilight (4 mm pupil), and 914 meters for daylight (3 mm pupil).
