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 small emission spot of ö160 ..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.
