-3- [ utz - sc03 36 _2 ] 2012/11/02 cautions (1) safety of laser light laser beam are extremely dangerous to human eyes. never look at laser beam directly and/or through optical lens. when han dling 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. nichia lds are classified in class 3b of iec60825-1 and 21 cfr part 1040.10 safety standards . it is absolutely necessary to take overall safety measures against user's modules, equipment and syst ems into which nichia lds are incorporated and/or integrated. (2) operating method the ld shall change its forward voltage requirement and optical output power according to temperature change. also, the ld will require more operation current to maint ain same output power as it degrades. confirm that electrical spike current generated by switching on and off does not exceed the maximum op erating current level specified herein above as absolute max rating . also, employ appropriate countermeasures to redu ce chattering and/or overshooting in the circuit. (3) static electricity static electricity or electrical surges will reduce and degrade the reliability of the lds. it is reco mmended to use a wrist strap or anti-electrostatic glove when handling the product. (4) absolute maximum rating active layer of lds shall have high current density and generate high electric field during its operat ion. in order to prevent excessive damage, the ld must be operated s trictly below absolute max rating. (5) others nichia lds described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment, communications equipment, measurement in struments and household appliances). consult nichia s sales staff in advance for information on the application s in which exceptional quality and reliability are required, particularly when the failure or malfunction of the lds may directly jeopardize life or health (such a s for airplanes, aerospace, submersible repeaters, nuclear reactor c ontrol systems, automobiles, traffic control equipm ent, life support systems and safety devices). the purchaser must acknowledge that any ld can be f ailed statically and must design its equipments fai l safe design. prior to use of the ld, please confirm that the ld, as described in nichias specifications, meets the life expectancy needs of, and provides the features required by the circuit and any related modules, equipment and/or systems. nichia prohibit purchaser from reverse engineering, disassembling, or taking any other steps to derive the structure or design of the ld. the appearance and specifications of the product ma y be modified for improvement without notice. the f ormal specifications must be exchanged and signed by both parties before large volume purchase begins. no unauthorized transmission or reproduction of thi s document, either in whole or in part, is permitte d.
