This disclosure describes techniques that isolate a flash module from a camera module and enable both to be housed underneath a single piece of transparent material such as glass. Using vitrography, small deformations are fabricated within the glass bulk surrounding the flash module. The boundary between the bulk and the vitrographed glass prevents light rays from traveling towards the camera module from the flash module. Compared to current techniques used to isolate the flash module from the camera module, the disclosed techniques reduce the cost and complexity of device assembly and produce better device performance and aesthetic.
