Abstract
An optical thin film filter may include a first set of filter layers with a first refractive index. The optical thin film filter may include a second set of filter layers with a second refractive index. A first set of thicknesses of the first set of filter layers, a second set of thicknesses of the second set of filter layers, the first refractive index, and the second refractive index may be configured to cause the optical thin film filter to achieve less than a threshold angle shift at a particular wavelength. The optical thin film filter may have an effective refractive index greater than or equal to 95% of a refractive index of a highest refractive index component material of the optical thin film filter.
