Webaspheric lenses. 3 Compound parabolic concentrators In the previous sections, an aspheric lens is used to collimate the LED. However, some LEDs emit light over a full hemisphere (i.e. ±90° beam divergence), making it impossible to collect the entire emission cone with a stock aspheric lens. For such sources, a compound parabolic concentra- WebApr 8, 2024 · The solution of optimal lens surface parameters of Powell prism and cylindrical lenses was the key to the combination optimization method we proposed. For Powell prism, the surface shape of an aspheric surface was determined by a higher-order equation. Let the vertex of the aspheric surface be the coordinate zero point.
