The Line Light design allows the structuring of light from round light source input to a line output configuration. The area of illumination coverage is defined by the length of the fiber optic line, the 68 degree light output cone on both axis and the stand-off distance. The output will be most uniform on the central axis and equal to the length of the fiber optic line. Thus, selection of the line light should be equal or slightly longer than the target. Decreasing the stand-off distance will increase the level of illumination.

Dual Light Lines, QDF type, can be utilized for two line scan camera use or with area array cameras to evenly illuminate relative flat area targets or to match up with the geometry of long targets such as cans, bottles, containers, rods, etc. Alignment relative to target geometry and angles of incidence are important parameters in obtaining an
optimum image.

The dual light line fiber optics are randomized at the input end to increase the uniformity at both output ends. Positioning dual light lines bi-laterally at 45 degree angles to the target allows for balancing the illumination over an area. This illumination balancing compensates for Inverse Square Law losses caused by the outside rays from each line light assembly traveling a longer distance. Thus, on a flat target surface the illumination from both outputs is summed and provides balanced levels of area illumination.
