A housing () for an electronic device () includes an optical film () having an optical transmittance for substantially normally incident light having a band edge separating first and second wavelength ranges, where the first wavelength range extends from about 400 nm to about 700 nm and the second wavelength range is at least about 100 nm wide and disposed between about 800 nm and about 1100 nm. For substantially normally incident light, an average optical reflectance of the optical film is greater than about 90% in the first wavelength range, and an average optical transmittance of the optical film is greater than about 80% in the second wavelength range. For at least one frequency in a range of about 0.1 GHz to about 90 GHz and for substantially normally incident radiation, the optical film transmits at least about 95% of the incident radiation.
