Abstract
An optical system includes an optical apparatus. The optical apparatus is for projecting a first projection image to a plane or detecting a first detected image of the plane. The optical apparatus includes a first image device, and a lens group. The first image device has an image surface having an image center. The lens group is disposed between the first image device and the plane and has a lens axis surface and an optic center. The optic center and the image center form a connection line. The plane has a tangent surface to an intersecting point of the connection line. The lens axis surface, the tangent surface, and an extension surface of the image surface substantially intersect at a straight line.
