17.02.2011 slp405-15-4p 3 of 3 safety of laser light ? laser light can damage the human eyes and skin. do not expose the eye or skin directly to any laser light and/or through optical lens. when handling the lds, wear appropriate safety glasses to prevent laser light, even any reflections from entering to the eye. focused laser beam through optical instruments will increase the chance of eye hazard. ? these lds are emitting invisible light. cautions 1. operating methode ? this ld shall change its forward voltage requirement and optical ouput power according to temperature change. also, the ld will require more operation current to maintain same ouput power as it degrades. in order to maintain output power, use of apc (automatic power control) is recommended. which use monitor feedback to adjust the operation current. ? confirm that electrical spike current generated by swithing on and off does not exceed the maximum operating current level specified her ein above as absolute maximum rating. also, employ appropriat countermeasures to reduce c hattering and/or overshooting in the circuit. 2. static electricity ? static electricity or electrical surges will reduce and degrade the reliability of the lds. it is recommended to use a wrist trap or anti-electrostatic glove when handeling the product. 3. absolute maximum rating ? active layer of lds shall have high current density and generate high electric field during its operation. in order to prevent excessive dam age, the ld must be operated striclty below absolute maximum rating.
