  • Page 5 Section 1 1 Laser Safety 1.1 General Information The laser light sources used in LMI Sensors are semiconductor lasers emitting visible light. LMI Laser Sensors have a 2/ll, 3R/llla or 3B/lllb classification depending on model. Class 2/ll and 3R/llla sensors are referred to as “products” indicating that they fully comply with the standards relating to laser products specified in IEC 60825-1 and U.S.
