2010 topical meeting on optical interference coatings: Manufacturing problem

Abstract

For the 2010 Manufacturing Problem, the participants were required to produce a filter that had normalincidence transmittances of 0.001, 0.01, 0.1, and 0.96, respectively, in four separate 60nm wide bands in the 400 to 700nm wavelength region. The problem is not unlike those that need to be routinely solved in the telecommunication industry. Nine groups submitted a total of 11 different filters for the contest. The number of layers in the filters received ranged from 28 to 678, and the total metric thicknesses varied between 4,038 and 22; 513 nm. The transmittances of the filters were measured at two independent laboratories. Some of the performances were quite close to the specifications. © 2011 Optical Society of America.
