-3- [ ytb-sc0002-10 ] 2012/04/25 cautions (1) safety of laser light laser light can damage the human eyes and skin. tunable laser beams are extremely dangerous to human eyes. do not expose the eye or skin to any laser light directly and/or through optical lens. when ha ndling the tunable laser modules, wear appropriate safety glasses to prevent laser light, even any reflection s from entering to the eye. focused laser beam through optical instruments will increase the chance of eye hazard. this nichia tunable laser module is classified in c lass 3b of iec60825 class 3b of iec60825 class 3b of iec60825 class 3b of iec60825- -- -1 1 1 1 and and and and complies with 21 cfr complies with 21 cfr complies with 21 cfr complies with 21 cfr 1040.10 and 1040.11 except for deviations pursuant to laser notice no. 50, dated june 24, 2007 1040.10 and 1040.11 except for deviations pursuant to laser notice no. 50, dated june 24, 2007 1040.10 and 1040.11 except for deviations pursuant to laser notice no. 50, dated june 24, 2007 1040.10 and 1040.11 except for deviations pursuant to laser notice no. 50, dated june 24, 2007. .. . it is absolutely necessary to take overall safety measure s against user's equipment and systems into which nichia tunable laser are incorporated and/or integr ated. (2) operating method please follow instructions manual for operation; ot herwise tunable laser will malfunction or character istics will be degraded. cable connectors must be connected firmly before su pplying electrical source. in addition electrical c able must keep connecting during operating the tunable laser. tunable laser characteristics especially laser long itudinal mode will be degraded by own feed back bea m or other reflected beam such as stray light. in order to mai ntain the laser characteristics, installing optical isolator or other substitute optical components are recommended (3) static electricity static electricity or electrical surges will reduce and degrade the reliability of the tunable laser. it is recommended to use a wrist strap or anti-electrostatic glove when handling the product. (4) absolute maximum rating active layer of tunable laser shall have high curre nt density and generate high electric field during its operation. in order to prevent excessive damage, the tunable lase r must be operated strictly below absolute max rati ng. (5) others nichia tunable laser described in this brochure is intended to be used for ordinary electronic equipme nt (such as holographic data storage, interferometer instrument s, analysis and measurement instruments). consult n ichia?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 tunable laser may directly jeopardize life or heal th (such as for airplanes, aerospace, submersible repeaters, nuclea r reactor control systems, automobiles, traffic con trol equipment, life support systems and safety devices). the purchaser must acknowledge that any tunable las er can be failed statically and must design its equ ipments fail safe design. prior to use of the tunable laser, ple ase confirm that the tunable laser as described in nichia?s 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 tunable laser. 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.
