LED1550E In Stock

The LED1550E by ThorLabs is a high-quality epoxy-encased LED designed for a wide range of applications. With its unique composition of heterostructures (HS) grown on an InGaAsP substrate, the LED1550E emits light with a precise spectral output centered at 1500 nm. Measuring at a compact 5 mm in diameter, this LED is encapsulated in a round clear epoxy casing, ensuring durability and reliability in any environment.

The LED1550E’s significant divergent angle requires the output light to be frequently focused through a lens for optimal performance. When used with an aspheric condenser lens, the LED1550E provides exceptional collimation of the emitted light. One of the standout features of the LED1550E is its parabolic reflectors, which effectively reduce the output divergence angle, resulting in a more focused and directed light output. This makes the LED a reliable choice for applications that require precise illumination. With a single-color output and an impressive output power of 2.0 mW, the LED1550E provides consistent and high-quality performance for the experimental needs of the user.
