In one embodiment, a semi-transparent reflector may include a multilayered photonic structure. The multilayered photonic structure includes a plurality of coating layers of high index dielectric material and a plurality of coating layers of low index dielectric material. The plurality of coating layers of high index dielectric material and the plurality of coating layers of low index dielectric material of the multilayered photonic structure are arranged in an [LH . . . (LH)N . . . L] structure. L is one of the plurality of coating layers of low index dielectric material. H is one of the plurality of coating layers of high index dielectric material. N is a positive integer. The multilayered photonic structure has substantially constant reflectance values for wavelengths of electromagnetic radiation in a visible spectrum over a range of angles of incidence of the electromagnetic radiation.
