This datasheet mainly introduces the features and characteristics of L2791 series infrared LEDs, including small emission spot, uniform emission, narrow directivity, etc. These products are suitable for applications such as automatic control systems, optical switches, and auto-focus.
This document describes the L2791 series of infrared LEDs, which utilize a current confined chip with a microball lens cemented to the surface. This design ensures high directivity and improved emission uniformity. A variant type without a microball lens, the L2791-03, is also available with an LED chip potted in resin.
