Abstract

A device for an image sensor is provided. The device includes a semiconductor device including a photo-sensitive region configured to generate an electric signal based on incident light. Additionally, the device includes an optical element including a first surface for receiving the incident light and a second surface opposite the first surface and turned towards the photo-sensitive region. The first surface and the second surface are tilted by a tilt angle relative to each other so as to modify a direction of propagation of the incident light passing through the optical element towards a center of the photo-sensitive region to compensate for a chief ray angle of the incident light.
