Abstract
An optical inspection system includes a brightness inspection module for inspecting the brightness of a light emitting element, an integrated inspection module for inspecting the near field optical characteristic and the beam quality factor of the light emitting element, and a far field inspection module for inspecting the far field optical characteristic of the light emitting element. As a result, the optical inspection system is space-saving and capable of reducing the distance and time of the movement of the device under test.
