Claim 19:
20. An optical system for receiving rays of light comprising a first optical module, the first optical module comprising:
a first optical element having a first optical axis, wherein the direction of rays of light pass through the first optical element in a first direction, the first optical element comprising:
a first surface, having a planar structure that is not parallel to the first optical axis, facing the first optical path-adjusting element; and
a second surface opposite to the first surface, having a non-planar structure that is not parallel to the first optical axis;

a first optical path-adjusting element corresponding to the first optical element, wherein the rays of light are redirected to a second direction by the first optical path-adjusting element;
a first driving assembly disposed at the first optical element, varying the structure of the second surface;
a first movable portion connected to the first optical element; and
a first fixed portion having a first housing, wherein the first housing has a first accommodating space, in which the first optical path-adjusting element is accommodated, and wherein the first movable portion is movable relative to the first fixed portion,
wherein the first optical element and the first optical path-adjusting element are arranged along the first optical axis,
wherein the first driving assembly includes a coil and a magnetic element,
wherein the second surface has a curvature that is adjustable by the first driving assembly, whereby the state of the rays of light passing through the first optical element is adjusted,
wherein the first driving assembly drives the first movable portion to move relative to the first fixed portion,
wherein when viewed along the first optical axis, the first driving assembly and the first optical path-adjusting element do not overlap,
wherein the first surface and the second surface are arranged along the first optical axis,
wherein the first optical path-adjusting element has a third surface, having a planar structure, facing the first optical element,
wherein the first surface and the third surface are parallel, and there is a gap between the first surface and the third surface, including gas inside the gap,
wherein the first optical module further comprises a positioning assembly disposed between the first optical element and the first optical path-adjusting element, for maintaining the gap between the first optical element and the first optical path-adjusting element,
wherein the positioning assembly overlaps the first optical element, the first optical path-adjusting element, and the first driving assembly when viewed along the first optical axis, and
wherein the first surface and the third surface both remain planar when the first driving assembly adjusts the curvature of the second surface.
