Abstract
The present disclosure provides a light homogenizing device and a biometric identifying device. The light homogenizing device includes a light homogenizing member and light-emitting units. The light homogenizing member includes a hole and protrusion structures. The protrusion structures are disposed on a first surface of the light homogenizing member and surrounding an outside of the hole. A circular inclined-plane is disposed between the hole and the protrusion structures and connected to the hole. The light-emitting units are disposed opposite to the first surface, and each light-emitting units transmits a light to one of the protrusion structures. The protrusion structures homogenize the light and outwardly transmit the homogenized light through a second surface of the light homogenizing member.
