Why choose infra-red LEDs

As part of our specialised production of high-performance optical components, infra-red LEDs are primarily used in combination with photosensors and provide a lower cost and longer lifetime than laser diodes.
Optoi infra-red LEDs are used in several sectors; however, their primary applications are in combination with our phototransistors and photodiodes in the production of encoders due to their high accuracy.
