24.07.2014 rlco -808- 1000-f 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 reflecti ons from entering to the eye. focused laser beam through optical instruments will increase the chance of eye hazard. ? this ld is emitting invisible light. cautions 1. operating methode ? this ld shall change its forward voltage requirement and optical ouput powe r according to temperature change. also, the ld will require more operation current to maintain same ouput power as it degrades. ? confirm that electrical spike current generated by switching on and off does not exceed the maximum operating current level spe cified herein above as absolute maximum rating. also, employ appropriat countermeasures to reduce chattering 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 damage, the ld must be operated striclty below absolute maximum rating.
