Abstract
Thin multilayer reflectors are described. In particular, thin multilayer reflectors that partially transmit blue light and reflect green and red light are described. The thin multilayer reflectors have a uniform left bandedge across each dimension of the film, wherein the location of the left bandedge varies in a range of no more than 10% of the average left bandedge across that dimension.
