Refractive optics; special design: two off axis Fresnel lenses fixed together in one piece, through an only molding process; the lens surface is made of concentric grooves which allow reducing the mass and volume of material that is required to realize the typical curved surface of conventional lenses. a Fresnel lens performs as an imaging optic. It means that moving the light source from the on-axis focus to any intra-focal position you can get different beam apertures, from the narrowest (focus position) to the widest (lens vertex position). By using the lens in an intra-focal position you will never perceive the real image of the light source but you just see a real round beam.
