                Infrared LED Lamp |  
              |  |  |  
              |  | This
                series of L680-xxAU is a GaAlAs LED mounted on a lead frame and
                encapsulated in various types of epoxy lens which offer
                different design settings. On forward bias it emits a high power
                radiation of typical 12mW with a peak wavelength of 680nm. |
