Abstract
Optical filters and methods of making optical filters are provided. The optical filter can include a first and second stack of layers. The first stack of layers can be configured to provide a cut-on edge for s-polarized radiation incident at a second wavelength value and a cut-off edge for s-polarized radiation incident at a third wavelength value. The second stack of layers can be configured to provide a cut-off edge for s-polarized radiation incident on the second stack of layers at a fourth wavelength value. Further, the fourth wavelength value can lie between the second wavelength value and the third wavelength value. Furthermore, a curve or line of full-width half-maximum (FWHM) values of the optical filter pass-band can define a first derivative with respect to angle-of-incidence values at at least one angle-of-incidence value that is substantially positive or substantially zero.
