Abstract
In the IR system the surface cosmetic quality is generally more critical than in the visible because the materials have generally low hardness and they tend to be affected by digs and scratches. These defects lead to a worsening in the optical quality and the image uniformity. The degradation effects depend on their dimensions and the surface position in the optical path. When the surface is near the focal plane their effects can be very evident because the defect dimension can be comparable to the beam one.
