Class I laser product
laser beam produced (the accessible emission) is always below the
Maximum Permissible Exposure value. Therefore, for Class 1 lasers the
output power is below the level at which it is believed eye damage will

Class 1 lasers may therefore be considered eye safe.
Class II laser product
