ABSTRACT:
A layered imaging stack for minimizing interference fringes in an imaging device. A polymer layer has one flat surface and a second opposed surface that has a surface roughness, R.sub.A, within the range of 0.5 .mu.m to 2.5 .mu.m. An adhesive layer provided on the roughened surface of the polymer layer has an index of refraction, n.sub.2, which differs from the refractive index, n.sub.1, of the polymer layer by at least 0.02. The multiplicative product of R.sub.A in .mu.m and the absolute value of n.sub.2 -n.sub.1, .DELTA.n, is within the range of from about 0.01 to 0.05.
