Abstract

The Moiré Deflectometry has been used with success for determination of refractive index, temperature gradients analysis, topography and parallelism control of surfaces and others, Nowadays it’s been applied this method to oftalmic lenses testing. However the Moiré Deflectometry applied to oftalmic industry need an automatization of the tests, which present some advantages in the quality control process made in industries working with its. In this work we present results of the spherical aberration and astigmatism coefficients, curvature radii and power measures, of different oftalmic lenses. This results are compared with other ones obtained by means of other techniques, in general, more expensive and tedious that Moiré Deflectometry.
