OPTICAL FILTER

Abstract:

In some implementations, an optical filter includes a first set of layers configured to pass light associated with a first wavelength range; a second set of layers configured to reflect light associated with at least one subrange of the first wavelength range; and a third set of layers configured to reflect light associated with a second wavelength range. In some implementations, the first wavelength range comprises an upper wavelength cutoff associated with a wavelength threshold, and the second wavelength range comprises a lower wavelength cutoff associated with the wavelength threshold. In some implementations, the optical filter includes a fourth set of layers configured to absorb a particular percentage of light in the first wavelength range.
