1. a camera system, comprising:

  • Optics stack, it comprises the first substrate and the second substrate that are fixed together in the stacking direction, and the first substrate comprises optical element;

    WithDetector in sensor base, whereinSecond substrate has sloped sidewall, and described sloped sidewall is coated with light absorbent,The angle that described sloped sidewall configuration reduces to be greater than camera system visual field enters the light quantity arriving detector;

    Second substrate wherein with sloped sidewall is the spacer substrate providing air-gap between optical element and detector;

    AndWherein sloped sidewall becomes knuckle.
