The measurement and analysis of the three-dimensional form of curved surfaces
The measurement and analysis of the three-dimensional form of curved surfaces
In an attempt to reduce manufacturing costs, contact lenses are manufactured using a cast moulding technique. If quality is to be maintained, it is essential that the mould components are manufactured to very high standards, with particular emphasis being placed on the curvature of the optical surfaces. If these surfaces are to be: accurately measured and described, then they must be considered in three dimensions. Several different :measurement instruments have been considered for this purpose, and three-dimensional numerical algorithms developed for assessment of the data from these instruments.

Abstract
In an attempt to reduce manufacturing costs, contact lenses are manufactured using a cast moulding technique. If quality is to be maintained, it is essential that the mould components are manufactured to very high standards, with particular emphasis being placed on the curvature of the optical surfaces. If these surfaces are to be: accurately measured and described, then they must be considered in three dimensions. Several different :measurement instruments have been considered for this purpose, and three-dimensional numerical algorithms developed for assessment of the data from these instruments.
