Angle-Independent Color Mirror (Contest Problem)
In conjunction with the 2013 Optical Interference Coatings (OIC) topical meeting of the Optical Society of America (Tucson, Arizona), an angle-independent color mirror was a subject of a design contest held. Michael Trubetskov (developer of OptiLayer Software) and Weidong Shen (user of the OptiLayer Software) won this contest by submitting color mirror designs with a zero color difference between normal incidence and all other incidence angles up to 60° as well as
the thinnest design. Many designers used OptiLayer Software in order to solve design contest problems. Learn more about the contest...
