Aconic reflector
Non-mathematically shaped light reflector From Wikipedia, the free encyclopedia

An aconic reflector refers to a light energy reflector that is not defined by a mathematical equation.[1]
Overview
Most light energy reflectors are based on conic sections such as parabolas, ellipses and circles. Aconic reflector is a generic term used to explain a reflective curve outside these groups. It literally means not conic.[2] They are usually created with the intention of generating a specific result not achievable using conic curves. At times they are created using combinations of definable curves but not always.[3] Modern light tracing software can generate curves using impact angles to generate a point cloud to define a required shape.

Application
Aconic reflectors are used in ultraviolet light UV curing devices to smooth light density for a more uniform curing pattern. They can be used to mask hot spots generated by the lamp envelope and cold areas created by shadows. They can be used to illuminate a specific shape at a given distance. Examples include a search light reflector that is intentionally designed to generate a divergent beam, or a reflective curve with the intention of generating an aesthetic light effect.[3]
If the reflective surface of a component is defined by a point cloud instead of being defined by a mathematical equation, it is likely an aconic reflector.[4]
