Method of and apparatus for adjusting optical component, and optical unit

摘要

An apparatus for adjusting an optical component has a reference beam unit (10) for emitting a reference laser beam L whose optical axis has established, and an optical axis unit (70) detecting the optical axis and focal point of a reflected beam La from a parabolic mirror (222) to which the reference laser beam L is applied. The optical axis unit (70) comprises first and second pinhole plates (74, 76) spaced a given distance from each other and having respective small holes (80, 90) defined therein.
