. One of the great difficulties in developing a text of this nature is that a broad, multidisciplinary background must be included in order that the reader can comprehend all of the subjeet matter readily. For this reason, the material presented on anatomy and physiology is orien ted toward the engineer or p978-1-4899-3596-0

Introduction to Laser Safety,period the hazards, particularly to the eye, were revealed, and subsequently much biological research was performed to delineate these hazards. By 1968 some national safety guides, written mostly for voluntary compliance rather than governmental regulations, were being used in the field of laser saf

Optical Radiation Hazards to the Skin,e are comparable except in the retinal hazard region (400–1400 nm). In the far-infrared and the ultraviolet spectral regions where optical radiation is not focused on the retina, skin injury thresholds are approximately the same as corneal injury thresholds. The probability of exposure of the skin i

Current Laser Exposure Limits,all discuss in detail the most recent set of limits, those promulgated by the ANSI Z-136.1 Standard, Safe Use of Lasers 1976. This set of limits is also identical to the threshold limit values (TLV’s) of the American Conference of Governmental Industrial Hygienists (ACGIH). These limits are essentia

Laser Hazard Classification,stinguish between lasers of differing risk, so that hazard control which would be required for very dangerous lasers would not needlessly be applied to small, relatively less hazardous, lasers. At present the laser hazard classification schemes used in standards promulgated by the American National
