Abstract
This disclosure provides an optical assembly, comprising a base body and a wave filtering apparatus. A first slot is disposed on an upper surface of the base body. A total internal reflection surface and a connecting part are formed in the first slot. The total internal reflection surface reflects collimated light formed by a first lens from a light emitting apparatus. The wave filtering apparatus comprises a first part removably connected to the connecting portion, and a second portion forming a beam splitting surface. The wave filtering apparatus has a light-pervious optical coating at least on the beam splitting surface of the apparatus, and is configured to split the collimated light reflected from the total internal reflection surface into a first beam and a second beam. The first beam travels towards the side where the third lens is located, and the second beam travels towards a photoelectric detection apparatus.
