Plastic injection molded lenses have improved its performance and, nowadays, are as usual as glass lenses in image forming devices. However, the manufacturing process induces the surface generation and the material transformation in the same stage. M

A large number of optical systems use diffusing thin films as active elements. Evaluation of the performance of an optical system that contains diffusing elements requires the characterization of the diffuser in its task environment. In this paper, a

We present a new strategy to calculate an optimized refractive freeform surface for illumination purposes with a LED source. The goal of this paper is to present a new iterative flux based strategy to design plastic lens for LED lighting solutions. T

In this contribution we present a compact system to create an illumination distribution with a constant aspect ratio 3:4 and FOV from 0. 4 to 1 degree. Besides, the system must delivery 40 W from 170 individual laser diodes placed in a regular 2-D ar

The Schmidt-Cassegrain configuration has advantages from the point of view of the packaging constraint but doesn't provide enough optical quality through the full field of view when a larger F-number (3.6) and a FOV of 1° are necessary to reach the

The process of comparing analogous images digitally obtained by means of a TV camera is studied. These images suffer degradation owing to defocusing, variation in the degree of coherence or because of later application of digital smoothing filters. A
