At a design angle of incidence, such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection band.

The wide reflection band may cover at least a portion of visible and infrared wavelengths. The multilayer optical film may include an additional optical layer which maybe be an anti-glare layer and/or may be an absorbing layer. The multilayer optical film is suitable for use as a window film.
