Abstract
An electronic device can include a housing defining an aperture, and an electromagnetic radiation emitter and an electromagnetic radiation detector disposed in the housing. An optical component can be disposed in the aperture and can include a first region of a first material having a first index of refraction, the first region aligned with the electromagnetic radiation emitter, a second region of the first material, the second region aligned with the electromagnetic radiation detector, and a bulk region surrounding a periphery of the first region and a periphery of the second region, the bulk region including a second material having a second index of refraction that is lower than the first index of refraction.
