Abstract
The present invention provides a method for fabricating small right angle prism mirrors, projecting system, and small right angle prism mirrors fabricated by a semiconductor process. The method comprises: coating a reflecting layer on a top surface of a glass substrate; forming an optical glue layer on a bottom surface of the glass substrate; utilizing a mold to form a 3D shape on the optical glue layer; exposing the optical glue layer having the 3D shape to solidify the optical glue layer having the 3D shape and combine the glass substrate having the reflecting layer and the optical glue layer having the 3D shape; removing the mold to form a small prism array; and dicing the small prism array to generate a plurality of small right angle prism mirrors.
