Download or read book Electron Beams Lenses and Optics written by A El-Kareh and published by Elsevier. This book was released on 2012-12-02 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron Beams, Lenses, and Optics, Volume I deals with the physics of electron beams, lenses, and optics and covers topics ranging from the paraxial ray in symmetrical electric fields to the analytical determination of electrostatic fields. The general properties of electrostatic lenses and the electrostatic immersion lens are also considered. Each equation except one is derived from first principles. To emphasize the physics of the discussions, elementary mathematics is used as much as possible. Comprised of eight chapters, this volume begins with an introduction to the laws that govern electron beams and light rays, including Snell's law. Some fundamental limitations to the analogy between electron optics and light optics are evaluated, together with electron rays in plane symmetrical and in rotationally symmetrical fields. Subsequent chapters explore the general properties of electrostatic lenses and electrostatic immersion lenses; electrostatic unipotential lenses; and formation of optical images by rotationally symmetrical magnetic fields. The final chapter is devoted to the symmetrical magnetic lens and its magnetic scalar potential, paying particular attention to the flux density along the z axis and factors to consider in the design of the pole pieces. This book will be of interest to students, practitioners, and researchers in physics.

Download or read book Contact Lenses in Ophthalmic Practice written by Mark J. Mannis and published by Springer Science & Business Media. This book was released on 2006-05-11 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even with the advances in intraocular lens technology and the growing diversity of refractive surgery techniques, the role of contact lenses in ophthalmic practice has only increased. This is due in part to the great strides in materials, technology, expanding applications (both refractive and therapeutic) for contact lenses, and the clear recognition that contact lenses will always be an important tool for the ophthalmologist. With the fitting of contact lenses as a medical art, requiring a thorough understanding of anatomy, physiology and optics of the eye, this practice is formulaic only in part. The rest of contact lens practice requires sound medical judgment and decision- making that comes only with "hands-on" experience. The authors address this need by starting with a didactic approach that incorporates frequently-asked questions and straightforward answers so that the ophthalmology resident, intermediate contact lens practitioner, and optometrist will find this to be an indispensable resource.
