Patent ID: RE40015

Claim:
An apparatus comprising a mounting substrate having a first light source and a second light source mounted thereon; a first aperture device having a first aperture and a second aperture; wherein the first aperture device can be aligned over the mounting substrate so that light from the first light source is emitted through the first aperture of the first aperture device and light from the second light source is emitted through the second aperture of the first aperture device; and wherein the first aperture device is adjustably mounted to the mounting substrate adjustable so that the first aperture device can move be aligned with respect to the mounting substrate; and the first aperture device is aligned with the mounting substrate to allow the emission of light from the first light source through the first aperture of the first aperture device and light from the second light source through the second aperture of the first aperture device by moving aligning the first aperture device with respect to the mounting substrate.
