1 infrared led small emission spot led using current con- ? ned chip l10596 series www.hamamatsu.com the l10596 is infrared led with a microball lens cemented to the current con ? nement chip surface. this combination ensures narrow directivity and uniform emission. in particular, the l10596-02 uses a lens cap that delivers even narrower directivity. as a variant type not using a microball lens, the L10596-03 is also available with the led chip potted with resin, which gives a sma ll emission spot of 160 ? m. the l10569 series has a light-re ecting layer inserted between the emission section and the gaas substrate, which increases the light output by 1.5 times (L10596-03: 1.3 times) that of conventional products. absolute maximum ratings (ta=25 c) electrical and optical characteristics (ta=25 c) parameter symbol condition value unit forward current i f 80 ma reverse voltage v r 3v pulse forward current i fp pulse width=10 ? s duty ratio=1% 0.45 a operating temperature topr -30 to +85 c storage temperature tstg * 1 -40 to +100 c * 1: the L10596-03 is guaranteed to resist temperature cycle test of up to 5 cycles. features applications automatic control systems high radiant output power : l10596/-02: 3.0 mw (if=50 ma typ.) optical switches uniform emission small emission spot: l10596: 400 ? m L10596-03: 160 ? m narrow directivity (l10596/-02) parameter symbol condition l10596 l10596-02 L10596-03 unit min. typ. max. min. typ. max. min. typ. max. peak emission wavelength p i f =50 ma 850 870 890 850 870 890 850 870 890 nm spectral half width ? i f =50 ma - 35 50 - 35 50 - 35 50 nm forward voltage v f i f =50 ma - 1.6 1.8 - 1.6 1.8 - 1.6 1.8 v pulse forward voltage v fp i f =0.45 a - 3.3 4.1 - 3.3 4.1 - 3.3 4.1 v reverse current i r v r =3 v - - 10 - - 10 - - 10 ? a radiant ux e i f =50 ma 2.1 3.0 - 2.1 3.0 - 5.0 6.5 - mw cut-off frequency * 2 fc i f =50 ma 10 map-p 10 15 - 10 15 - 10 15 - mhz * 2: frequency at which the radiant output drops by 3 db relative to the output at 100 khz
