Abstract
An electronic device can include a housing defining an aperture and at least partially defining an internal volume of the electronic device, an electromagnetic radiation emitter and an electromagnetic radiation detector disposed in the internal volume, and an optical component disposed in the aperture. The optical component can include a first and second transparent portions disposed above the electromagnetic radiation detector and the electromagnetic radiation emitter, and an opaque portion disposed between the first and second transparent portions and extending a thickness of the optical component. The first transparent portion, the second transparent portion, and the opaque portion can define a flush exterior surface of the electronic device.
