A lenslet module configured to receive light from a two dimensional laser array having laser sources disposed in a plurality of rows and columns, comprises a transparent substrate that has a light-receiving surface and a light-emitting surface. A plurality of light-receiving lenslets are disposed on the light-receiving surface of the substrate, such that each lenslet corresponds to a laser source in the laser array. An emitting lens is disposed on the light-emitting side of the substrate, in order to focus light collected by the receiving lenslets at a given focal length located at a distance away from the emitting lens. The light receiving lenses and the light-emitting lens are preferably configured as plano-convex lenses.
