Findings from Guangdong University of Technology Provides New Data about Optical Research (Influence of optical aspheric parameters on obtaining uniform rectangular illumination)

By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Optical Research have been presented. According to news reporting from Guangdong, People's Republic of China, by VerticalNews journalists, research stated, "The research focuses on designing a suitable aspherical surface to create a rectangular and uniform illumination by studying the influence of optical aspheric parameters. The geometrical optics is used to analyze the transmission equation of the LED beam and the minimum divergence angle is calculated out by numerical simulation."

The news correspondents obtained a quote from the research from the Guangdong University of Technology, "Furtherly, the relationship between the divergence angle and some parameters of the lens is researched by using the normal equation for conic aspheric. Then the K-2 of the lens's second surface is modified and verified by optical tracing simulation software (TracePro) to a rectangular and uniform illumination on the receiver. The result indicates that ellipsoid can get a better uniform rectangular illumination than paraboloid and hyperboloid. The final divergence angle is 5.997 mrad, close to the theoretical calculation value 1.92 mrad, and the illumination uniformity of the predetermined illumination area on the receiver is better than 93.02%."

According to the news reporters, the research concluded: "It is expected that this method will have great potential for other lighting applications."
