wp.optics.arizona.eduOct 31, 2008 · process, melted plastic is pressed into a mold (spherical or aspheric), then cooled and ejected from the mold. The injection molding process must be carefully controlled, especially the flow of the plastic and cooling, since stress patterns can show up within the lens.

Zernike Polynomials - University of Arizona
wp.optics.arizona.eduZernike Polynomials 1 Introduction Often, to aid in the interpretation of optical test results it is convenient to express wavefront data in polynomial form. Zernike polynomials are often used for this purpose since they are made up of terms that are of the same form as the types of aberrations often observed in optical tests (Zernike, 1934).

Overview of various methods for measuring a lens focal length
wp.optics.arizona.eduThis technique uses the Talbot effect: the image of a coherent wave with 2D periodic amplitude distribution, incident upon a diffraction grating, is regularly repeated. The distance between each self-image is the Talbot length ∆. If the wave interferes with another wave diffracted by a grating with a different spatial period, it creates a Moiré
