ColorWedge™

When standard dichroic filters/mirrors are used to separate light into different color beams in HTPS and LCOS architectures, unavoidable spectral shifts of the dichroic coatings may result in noticeable color non-uniformity in projected images. ColorWedge™ dichroic filters/mirrors consist of a customized gradient type coating to compensate for the color non-uniformity, resulting in superior color images of projection display systems. ColorWedge™ dichroics are produced with the same sputtering deposition technology as the standard dichroic filters/mirrors and bear all superior quality features of sputtered dichroic filters.
