A self-illuminating camera includes a camera and an illuminator. The camera includes an image sensor and a first lens of a pair of two identical lenses. The illuminator is adjacent to the camera and includes a light source and a second lens of the pair of two identical lenses. The illuminator has a field of illumination that at least partially overlaps a field of view of the camera.

Self-illuminating camera

A chip-level camera includes an image sensor; a concave L1 lens element on an inside surface of a first substrate; a convex L2 lens element on a first surface of a second substrate; a diaphragm stop on a second surface of the second substrate or on a first surface of a third substrate, the diaphragm stop between the second and third substrates; a convex L3 lens element on a second surface of the third substrate spaced from the image sensor; a first spacer holding first substrate at a predetermined distance from the second substrate; and a second spacer holding the second substrate a predetermined distance from the image sensor. In embodiments, lens element L1 has concave aspheric radius of R1, and lens L2 convex aspheric radius of R2, such that 1.3<ABS(R2/R1)<2.2 and/or lens L3 has convex aspheric radius R3, where 1.1<ABS(R3/R1)<2.4.
