Subsequently, the characteristics of these lenses and the equations that describes them are studied. Finally, several implications of these lenses are studied, such as freeform lenses, optical systems, axicons, telescopes and more. Scenarios with on-axis objects and off-axis objects are considered. Cases where the object is real or virtual, and the image is real or virtual are also presented. The book is a valuable resource for industrial specialists and academics in lens design and optics, and an insightful guide for optical physics students.

Download or read book Design Fabrication and Metrology of Precision Molded Freeform Plastic Optics written by Likai Li and published by . This book was released on 2014 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main focus of this dissertation is to seek scientific knowledge and fundamental understanding of molding process for freeform optical lens fabrication by integrating freeform optical design, precision freeform molding making, numerical modeling of polymer lens forming process, and evaluation of the molded freeform optics. Compared with conventional optics, freeform optics provides more flexibilities and better performance. However, due to the complex nature of freeform optics manufacturing processes, the productivity and quality is difficult to improve, which subsequently results in higher manufacturing cost. Therefore, in order to create affordable freeform lenses with high quality, the method combining ultraprecision diamond machining and optical molding is proposed. Ultraprecision diamond machining is a process that allows us to generate precision freeform optical features on mold surfaces without post polishing, while microinjection/compression molding is proven high volume manufacturing process used to reduce production cost. The diamond machining for both regular metal materials and brittle materials are discussed to obtain high quality molds with optical finish. In addition, two novel process designs are presented to fabricate hybrid glass-polymer achromatic lenses using compression molding and injection molding, respectively.

Download or read book Lens Design Fundamentals written by Rudolf Kingslake and published by Elsevier. This book was released on 2012-12-02 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of this book is devoted to a study of possible design procedures for various types of lens or mirror systems, with fully worked examples of each. The reader is urged to follow the logic of these examples and be sure that he understands what is happening, noticing particularly how each available degree of freedom is used to control one aberration. Not every type of lens has been considered, of course, but the design techniques illustrated here can readily be applied to the design of other more complex systems. It is assumed that the reader has access to a small computer to help with the ray tracing, otherwise he may find the computations so time-consuming that he is liable to lose track of what he is trying to accomplish.

Download or read book Theory and Design of Freeform Gradient Index Optics and Applications in Progressive Addition Lenses written by Nicholas S. Kochan and published by . This book was released on 2022 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The progressive addition lens (PAL) is an eyeglass which continuously changes optical power as the gaze of the wearer moves downwards through different viewing zones. The astigmatism must be corrected within viewing zones of the lens. Correction of this astigmatism with power addition defines the PAL design space and is limited for homogeneous PAL designs. The present work identifies the ways in which gradient index (GRIN) lenses can be implemented as PALs. It is shown that the design space for the GRIN PAL is at least as large as that for the homogeneous PAL. It is derived that the contributions to power and astigmatism come from local constant, linear, and quadratic terms of surface and GRIN parametrized in the moving frame of the ray. This behavior constitutes freeform GRIN generalized Coddington's equations (GCE) developed in this work. There are four types of contributions. The GCE are applied analytically to three test cases to demonstrate consistency of derived theory with known ray behavior for homogeneous and GRIN distributions. Because it may not always be possible to know the GRIN distribution in terms of the moving frame of the ray, the GCE are reparametrized from ray coordinates into global coordinates. The reparametrization is numerically analyzed for the four types of GCE contributions, and assumptions and evaluation residuals are deemed sufficient for the range of powers relevant to PAL design. The GCE in global coordinates enable the simultaneous optimization of freeform GRIN and freeform surface in a PAL. Zonal performance can be evaluated by GCE without raytracing, enabling analytical design. A design study is provided showing the convergence of optimization for freeform GRIN and freeform surface PAL designs. Raytrace performance analysis supplements developed theory and design methods in this work. The performance contributions due to zonal constant and second order terms of surface and GRIN are those which dominate the design result. This is apparent because the optimized PAL with freeform surface and freeform GRIN have surface and GRIN bearing the same form of profile. The analysis of the GCE terms shows that for a given effect on power or astigmatism, terms dependent on zonal linear profile contributions require larger sag and index variation than contributions from curvature. It is shown that the freeform GRIN PAL design space is at least as large as that of surface PALs. The optimization of a freeform GRIN PAL with a freeform surface shows contributions to optical performance are dominated by zonal quadratic term variation in practice. Equivalent zonal linear profile sag and index variation contributes smaller performance for given index and sag variation. When the linear term contribution is negligible, performance contribution to correction of power and astigmatism is the approximate linear combination of surface and GRIN contributions. For design optimization, the zonal quadratic and constant terms of surface and GRIN are those which dominate performance contribution on propagation through the lens. To complement analysis of optical performance, it is shown that an embedded optical surface can be converted to GRIN directly while maintaining input and output ray trajectory. This enables designing a GRIN by first designing a cemented surface homogeneous optic and applying the conversion method. Consistent with framework of GCE, freeform GRIN PAL and freeform homogeneous PAL are fabricated to the same performance prescription. A scanning Shack-Hartmann wavefront sensor is built to evaluate performance. The PAL is scanned and target performance is validated by polynomial fitting performance measurement. Oscillatory performance deviation is observed in the GRINPAL. Oscillatory variation and random variation in index of refraction are each observed as a deviation from design in the manufactured GRIN PAL. These are due to inkjet printing artifacts, and are further characterized by using phase-stepping interferometry and transmission deflectometry. Manufacturing artifacts significant for performance validation are 1.5-2mm mid-spatial frequency (MSF) vertical bands on the GRIN PAL and high-spatial freqency (HSF) fluctuation due to printing on the scale of 100-200 æm period. Both artifacts have amplitude on the scale of 1 - 2 × 104 index of refraction. Analysis is provided showing that MSF contribution to performance departure scales quadratically with spatial frequency, and that the oscillations measured are on a scale which contributes diopter-scale oscillatory performance departure. Performance errors from polynomial fit in homogeneous PAL are on the scale of desired 0.1-0.125 D performance tolerance, but are single diopter scale for the GRIN. Proper performance is evident in the GRIN PAL, but index fluctuation is approximately ten times too large. This thesis identifies the need to minimize this error"--Pages xi-xiii
