Section9 Requirements from Regulations and Standards Definitions of Laser Classification  For Europe Laser Product Classifications Class Description Class 1 Lasers which are safe under reasonably foreseeable conditions of operation. Class 2 Lasers emitting visible radiation in the wavelength range from 400 nm to 700 nm. Eye pro- tection is normally afforded by aversion responses including the blink reflex.
Page 202 Section9 Requirements from Regulations and Standards Class FDA definition ANSI description Class IIIa/3a Limits to products that have emissions in the Class 3 lasers are divided into two sub- visible spectrum and that have beams classes, 3a and 3b. A Class 3 laser may be where the total collectable radiant power hazardous under direct and specular reflec- does not exceed 5 milliwatts.
