Disclosed is a composite array camera lens module, including: a first lens layer disposed at a position from a diaphragm toward an object space having a first-type lens and a second-type lens; a second lens layer disposed at a position from the diaphragm toward an image space having a third-type lens and a fourth-type lens, wherein the first-type lens and the third-type lens are positive lenses and form a first camera lens with a first effective focal length, and the second-type lens and the fourth-type lens are a negative lens and a positive lens, respectively, and form a second camera lens with a second effective focal length less than the first effective focal length; and an image sensor arranged at a side of the second lens layer away from the diaphragm, wherein the first lens layer, the second lens layer and the image sensor are designed to be parallel flat planes.

A mixing light module includes a matrix, a fluorescent film, and a plurality of micro-structures. The matrix includes an incidence surface, an emission surface and a reflective surface. The fluorescent film disposed on or above the emission surface has an upper surface and a lower surface and includes a plurality of fluorescent particles. The matrix receives a first light having a first wavelength, and the reflective surface reflects the first light to make the first light to be emitted from the emission surface. Since the plurality of fluorescent particles receives a part of the first light from the emission surface, the plurality of fluorescent particles is excited to emit a second light having a second wavelength. The second light and the first light are mixed into a predetermined light. The plurality of micro-structures is used to make the first light or the second light uniform.

The present invention discloses a dual-lens hybrid diffractive/refractive imaging system comprising: a first lens including a concave surface and a convex surface; and the second lens including a convex surface and a concave surface. The concave surface of the first lens is an objective surface facing the object. The convex surface faces the convex surface of the second lens, while the concave surface of the second lens faces the charge-coupled device (CCD) through a filter. Any surface of the first lens and the second lens is spheric or aspheric. Moreover, the imaging system comprises at least one diffractive surface, referred to as a hybrid diffractive/refractive surface, formed on any surface of the two lenses. Therefore, aberration is eliminated and image quality is improved without increasing the number of lenses.
