SELFOC® Lens Array (SLA)

The SELFOC Lens Array is used in 1:1 image transfer applications. The arrays are composed of one or more rows of lenses. The images from adjacent lenses overlap and form a continuous erect image. The SLA's short total conjugate (TC), ranging from 9 to 80 mm, allows the designer to decrease the optical path length and, thus, reduce the overall size of the system.
