During Chemical Vapour Deposition the small crystallite grains align with thedirection of growth锛 and are

normal to the thickness of the sheet produced. For windows of normal thickness and aspect ratios the alignmentof the grain therefore is rarely a problem as they are cut from the grown sheet such that within an optical windowthe grains align perpendicular to the surfaces. This is optimum orientation for lowest internal absorption andscatter.

With prisms锛 the cutting direction requires more consideration. It isrecommended that the thickness of the stripmaterial corresponds to the apex height of the prism. This ensures optimum crystallite orientation for most usual

prism applications.

For typical 45° prisms the most obvious use of material is shown in (A) but it

should be noted that this is not the optimum orientation.

The best choice is (B) and it also permitsa higher limit on prism size orconverselyallows thinner stock to be used. There iswaste at the ends of the strip but this issmall and so it may not be quite aseconomic as (A).

Cutting in direction (C) where the entire light beam runs at 90° to the grain

structure should be avoided completely if at all possible.Note that maximum available thickness of ZnSe and ZnS (FLIR) is approximately 60mm. Maximum availablethickness of ZnS Cleartran is approximately 30mm
