2 sld302v electrical and optical characteristics (tc: case temperature, tc = 25 c) handling precautions eye protection against laser beams the optical output of laser diodes ranges from several mw to 1w. however the optical power density of the laser beam at the diode chip reaches 1mw/cm 2 . unlike gas lasers, since laser diode beams are divergent, uncollimated laser diode beams are fairly safe at a laser diode. for observing laser beams, always use safety goggles that block infrared rays. usage of ir scopes, ir cameras and fluorescent plates is also recommended for monitoring laser beams safely. ? 1 wavelength selection classification type sld302v-1 sld302v-2 sld302v-3 wavelength (nm) 785 15 810 10 830 10 type sld302v-21 SLD302V-24 sld302v-25 wavelength (nm) 798 3 807 3 810 3 a p c a t c safety goggles for protection from laser beam ir fluorescent plate optical material optical power output control device temperature control device lens laser diode optical boad item symbol conditions min. typ. max. unit ith iop vop p imon ? // ? x, ? y ?? d threshold current operating current operating voltage wavelength ? 1 monitor current radiation angle (f. w. h. m. ? ) positional accuracy differential efficiency p o = 180mw p o = 180mw p o = 180mw p o = 180mw v r = 10v p o = 180mw p o = 180mw p o = 180mw 770 0.65 150 350 1.9 0.3 28 12 0.9 200 500 3.0 840 40 17 50 3 ma ma v nm ma degree degree m degree mw/ma perpendicular parallel position angle ? f. w. h. m. : full width at half maximum
