Miniaturized Light Module with High Collimation
Introduction
Conventionally, it is difficult to collimate an LED beam. Using the fiber collimator with UV curing adhesive lens, this light module achieves a good collimation, and a more uniform power distribution. In the cases of miniaturized biomedical detection, a light source can be replaced with such module, enabling the realization of a micro total analysis system.
