Abstract
Optical films, such as reflective polarizer films, and optical systems including the optical films are described. An optical system includes one or more optical lenses having at least one curved major surface, a partial reflector, and a reflective polarizer. For a substantially normally incident light in a predetermined wavelength range extending at least from about 450 nm to about 600 nm: the partial reflector has an average optical reflectance of at least 30%, and the reflective polarizer has an average optical reflectance Rs for a first polarization state, an average optical transmittance Tp for an orthogonal second polarization state, and an average optical reflectance Rp for the second polarization state, where Tp≥80%, Rp≤1%, and 50%≤Rs≤95%.
