PPT-Lens Aberrations

Aberration a departure from the paraxial limit Paraxial limit 1 Rays are kept close to the optic axis 2 Small angle approximation 1 st Order 5 th Order 3 rd Order. The Cartesian ellipsoid . produces a stigmatic image of only one object point. Normal eye and most of optical systems are not free from aberration. . . Reference sphere:. . a circular arc centered on the image point with a radius equal to the image distance. A. .. L. Ponomarev. 1,. 3. , . K. George. 1,3. , . F. .. A. Cucinotta. 3. 1.

Athermal lens mount design A tutorial on the use of ZEMAX and Solidworks in athermal lens mount design By James Champagne OPTI 521 – Optomechanical Engineering Fall 2010 Overview Goal is to design a lens mount to compensate defocus caused by temperature changes The lens is a transparent, biconvex, crystalline structure placed between iris and the vitreous. . It has got two surfaces: the anterior surface is less convex (radius of curvature 10 mm) than the posterior (radius of curvature 6 mm).. : 2967-2974(2004) Panani et al: Chromosomal Aberrations in Primary Bladder Cancer 2969 Figure 1.A,B,C.
