Knife edge testing of a lens with spherical aberration.

Product Description

Download scientific diagram | Knife edge testing of a lens with spherical aberration.  from publication: Optical aberrations measurement with a low cost optometric instrument | A simple experimental method for measuring optical aberrations of a single lens is proposed. The technique is based on the use of an optometric instrument employed for the assessment of the refractive state of the eye: the retinoscope.
