LED ILLUMINATION FOR LINE SCAN CAMERA

摘要

An illumination system that includes: (i) a first rectangular light emitting diode array that emits quasi-collimated light; and (ii) first concentrating optics that comprises at least one total internal reflection lens portion and at least one refractive lens portion. The quasi-collimated light from the first rectangular light emitting diode array is directed by the first concentrating optics towards an object to form a line of light on the object.
