Abstract:
1. A device, comprising: a first light source for emitting a first light signal operating in a first region of a light spectrum; a second light source for emitting a second light signal operating in a second region of the light spectrum, wherein the first region and the second region differ; and a first optical device providing a coaxial optical path of the first light signal and the second light signal, wherein a relative position of the first optical device to the first light source and the second light source provides a first focal point of the first light signal to be in at least a proximate location of a second focal point of the second light signal, and wherein the relative position of the first optical device maintains the first focal point at the proximate location of the second focal point after a focal adjustment of the first focal point or the second focal point.
