L10596 Datasheet, PDF (1/4 Pages) Hamamatsu Corporation – Small emission spot LED using current con-ned chip

Infrared LED
L10596 series
Small emission spot LED using current con-
¿ned chip
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 φ160 —m. The L10569 series has a light-reÀecting 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.
