  • Patent number: 6987915
    Abstract: An embodiment described herein provides a technique to determine a focus point of a lense. Light is directed from a light source through the lense and onto a target surface. The light source and target surface may be positioned on opposite sides of the lense. The target surface may correspond to the position of where a primary light source for the particular application is to be located. A reflection passing through the lense from the reflective target surface may be located. A determination is then made as to whether the position where the reflection was located also could also corresponds to a focus point for the lense, if the primary light source was to be located at or near the target surface.
