OPTICAL SYSTEM

The present invention relates to an optical system for imaging using a camera and a light source of a handheld device, wherein the optical system comprises a transparent optic defining an optical volume, the transparent optic comprising a first main face adapted for positioning an object to be imaged, the transparent optic adapted to admit into the optical volume a light emitted by the light source for illuminating the object and wherein the transparent optic is adapted to admit the light having interacted with the object into the optical volume and turn the light inside the optical volume such that the light is internally reflected within the optical volume and exit the optical volume to be incident onto the camera.
