摘要：
A composite optical element is provided. The composite optical element includes a plurality of optical elements, in which at least one of the optical elements is formed of an element modifying an optical path and the other optical elements are bonded to an incident surface and/or exit surface of the element modifying the optical path with a low refractive index material layer in between.
