MULTIBEAM LIGHT EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a multibeam light emitting device by which a distinct image can be obtained by restraining the lowering of light quantity while using a general purpose semiconductor laser. SOLUTION: A 1st beam and a 2nd beam emitted from the 1st semiconductor laser 11a and the 2nd semiconductor laser 11b are made parallel beams having a specified distance between the beams and made parallel with each other by passing through a 1st collimating lens 13a and a 2nd collimating lens 13b, and also the parallel beams are refracted by a lens 14 for adjusting a distance between beams and made parallel beams having a shortened distance between the beams and made parallel with each other.
