Abstract
A thin optical imaging module of a biometric apparatus includes a first glass substrate, a first optical prism film, a second optical prism film, and an image sensor. The first glass substrate further includes a fingerprint imaging area, a vein imaging area, a contact surface, a reflective interface, and an attaching surface. The first optical prism film adhered to the attaching surface is located under the fingerprint imaging area. The second optical prism film is adhered to a position under the first optical prism film. The image sensor disposed in correspondence to the first glass substrate is located under the attaching surface.
