38 Caution for Using Laser Diodes (1) A laser beam is harmful to human eyes Never look at active laser directly or through lens (2) Caution must be exercised in preventing electrostatic damage while handling the laser diode To ensure human grounding (via 1 MΩ), use a conductive mat on the floor, conductive sole shoes, conductive containers, etc Always ground the tip of solder iron (3) Laser diode can be damaged by abnormal pulses from nearby equipment For example, fluorescent lamps should never be turned on/off near laser diodes (4) Never exceed the absolute maximum rated values It is especially important not to exceed the absolute maximum output even momentarily (5) Check the transition characteristics of the entire driving circuit including the power supply Take appropriate measures to avoid events such as spike current generated when the power switch is turned on/off which may exceed the laser diode's maximum rating (6) We recommend keeping the actual design targets below 2/ 3 the maximum ratings (7) Appropriate protective circuitry must be provided in each laser circuit (8) Attention must be paid to providing adequate means for heat dissipation A copper plate of 50 mm 50 mm 2 mm or similar heat dissipation device of adequate dissipation should be used as a heat sink The following warning labels are used to indicate the danger of laser beams Laser beam not to look at or touch a laser beam Maximum output 400 Class 3B Laser products! Caution for Safety! DANGER Do not touch or look at a laser beam directly It is in danger of a injury to eyesight or outer skin in the worst case 36
