  • Aspheric Lenses for Imaging
    Publication number: 20100059677
    Abstract: A lens for Terahertz imaging that has a transparent body defining at least a first and a second lens surface. The lens body is arranged such that light incident to the lens refracts at the first lens surface, propagates through the body to the second lens surface and refracts at the second lens surface. The angle of deviation of light at the first lens surface substantially equals the angle of deviation of light at the second lens surface.
