## Abstract

A camera module comprises an image sensor and a lens module disposed on the image sensor. The lens module comprises a top glass structure at top of the lens module. The top glass structure includes a first glass substrate, a second glass substrate, and a baffle disposed immediately between the first and the second glass substrates. The top glass structure is an outermost layer of the camera module. The lens module also comprises a bottom glass substrate at bottom of the lens module. The bottom glass substrate is disposed on the image sensor.

## Claims
