Collimating detection apparatus and optical module packaging apparatus using the same |
摘要 |
Provided is a collimating detection device for use in fabricating a semiconductor laser diode module, wherein the collimating detection apparatus discriminates using a light output difference between a case where the beam emitted from a laser diode becomes parallel light through a collimating lens and a case where the parallel light is not made, using properties of Fabry-Perot etalon that changes optical power of the output beam as an angle of an incident beam is changed.
