Abstract:
An optical scanner head for use in a scanner device, comprising:a body portion including a first pathway to discharge light and a second pathway to receive light, the second pathway disposed at an angle from the first pathway, wherein the angle forms a predetermined focal point position of the optical scanner head; wherein light discharged from the first pathway is isolated from the second pathway, the first and second pathways forming a centralized opening, comprised of side-by-side holes, in a front face of the optical scanner head; wherein each pathway is configured with an identical cross-sectional shape, the shape chosen from the group consisting of circular, oval, and of a geometry having at least three sides; wherein each of the pathways have corresponding front and rear ends, the front ends disposed alongside each other and the rear ends disposed laterally from each other; wherein one pathway and an adjoining pocket is adapted to receive the photoemitter assembly and the other pathway and an adjoining pocket is adapted to receive the photodetector assembly; and wherein each pathway and adjoining pocket is identical, each pocket having a respective upstanding, centrally disposed pin projecting from the floor that is aligned with the photo axis of the respective pathway.
