摘要 |
An electromagnetic radiation emitting assembly is disclosed and which includes a supporting substrate having opposite first and second surfaces and having an area formed therein which allows electromagnetic radiation to pass therethrough; a reflector positioned adjacent to the second surface of the substrate and oriented in a given position relative to the area formed in the substrate; and an electromagnetic radiation emitter mounted on the second surface of the substrate and which emits a source of electromagnetic radiation which is reflected by the reflector through the area formed in the supporting substrate. An electromagnetic radiation receiver is also described. |
