Abstract: An optical mechanism is provided, including an optical member, a reflecting element, a holder, and a housing. The optical member includes a first optical lens and a second optical lens. Light propagates into the optical mechanism in a first direction and is reflected by the reflecting element to propagate through the first and second optical lenses in a second direction. The holder supports the first and the second optical lenses, wherein the first and second optical lenses define an optical axis parallel to the second direction. The housing has a lower cover and a top cover, wherein the holder is accommodated in the housing. The first optical lens is closer to a light-entering end of the optical member than the second optical lens, and the first optical lens is larger than the second optical lens.
