Abstract
A system and method for scanning a wide band beam is presented. An apparatus includes a pair of prism triplets. Each prism triplet includes a first wedge prism, a second wedge prism and a third wedge prism all formed with different optical materials. In operation, a beam passing through the wide band team scanning apparatus first passes through the first, second and third wedge prisms of the first prism triplet. The beam then passes through the wedge prisms of the second prism triplet in a mirrored order (the third, then second, then first wedge prisms) than that of the first prism triplet. This apparatus with two prism triplets allows wide band light transmitted through it to emerge with its plurality of different wavelengths of light travelling in the same direction to equalize net dispersive effects each of different wavelengths.
