The first three chapters present an introduction to the principles of optics and the unique aspects of the infrared region of the wavelength spectrum. This foundation makes it possible for those readers who are not optical engineers to acquire the background information needed for a treatise on infrared zoom lenses. Chapter 1 presents overall system considerations involved in establishing the requirements for an application that includes an optical system as one of its elements. Chapter 2 sets forth the basic fundamentals of optics involved in the design and analysis of optical systems. Chapter 3 presents the optics features that are unique to the infrared region of the spectrum. Chapter 4 discusses some of the optical design techniques that may be utilized in the optical design of infrared systems.
A camera lens also known as photographic lens or photographic objective is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera , a video camera , a telescope , a microscope , or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths , apertures , and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct as much as possible the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a design that is suitable for photographic use and possibly mass production. Typical rectilinear lenses can be thought of as "improved" pinhole "lenses".

- Мидж зло посмотрела на него и протянула руку. - Давай ключ. Я жду.
Все внимание Беккера сосредоточилось на открытой двери, и он забыл о жгучей боли в ногах. Задние колеса уже остались за спиной - огромные, доходящие ему до плеч скаты, вращающиеся все быстрее и быстрее. Беккер рванулся к двери, рука его опустилась мимо поручня, и он чуть не упал.
ГЛАВА 10 - Энсей Танкадо мертв? - Сьюзан почувствовала подступившую к горлу тошноту. - Вы его убили. Вы же сказали… - Мы к нему пальцем не притронулись, - успокоил ее Стратмор. - Он умер от разрыва сердца.
