A revised and thoroughly updated edition of THE definitive guide to identifying dragonflies in Europe.

"A ground-breaking identification guide ... the perfect marriage of artistic excellence, deep knowledge and, dare I say it, of scientists'' genuine affection." BRETT WESTWOODThis brand new illustrated field guide covers all 47 species of ladybird occurring in the British Isles in a handy and easy-to-use format. Twenty-seven species are colourful and conspicuous and easily recognised as ladybirds; the remaining species are more challenging, but the clear illustrations and up-to-date text in this guide will help to break down the identification barriers. A useful introduction provides an overview of ladybird ecology, tips on studying and recording, and suggested sites for finding ladybirds. The main part of the book comprises detailed species texts, covering field characters, food, habitats, suggested survey methods, ranges, conservation statuses and distribution trends. An illustrated at-a-glance identification guide and helpful pointers for differentiating similar-looking species are also included. With 102 colour photographs and 47 distribution maps, combined with Richard Lewington''s peerless artwork, this is the definitive guide to one of our most cherished and charismatic insect groups.

Provides a concise, self-contained, and rigorous overview of the different processes, techniques, and configurations used to develop optical biosensors. Several representative applications in many different fields are provided. Other practical aspects, such as commonly used biorecognition elements are also presented.

Serves as a reference guide to the primary results, explanations, and interpretations of quantum mechanics that foregoes the introductions, derivations, and conceptual discussions found in most textbooks on the subject.

An Introduction to Familiar Plants Animals and Outstanding Natural Attractions.

Field guide introduces common plants and animals and highlights the diversity of species found in Colorado. More than 350 full color illustrations and maps featuring the major wildlife viewing destinations in different parts of the state. Checklists and full indices allow citizen scientists and nature watchers to track their viewing experiences.

Provides an overview of the basic principles of solid state physics, focusing on the practical aspects and device applications. Topics include crystal structures and dynamics, band structures, quantum structures, semiconductors, superconductors, and magnetism. Equations and diagrams effectively convey the concepts that form the core of this field.

Distils the critical information on infrared principles, techniques, and systems. The book covers all aspects of infrared optics, including monochromatic and chromatic optical aberrations. It also provides a comprehensive introduction to the optical, mechanical, and thermal properties of infrared materials.

Guide for antique buyers and dealers to spot the real thing.

Covers all aspects of IR optics, including monochromatic and chromatic optical aberrations as well as important concepts such as depth of focus, depth of field, hyperfocal distance, warm shields, aspheric surfaces, and kinoforms.

Crystal growth is the art and science of growing crystals to facilitate high-technology applications in lasers, semiconducting devices, computers, magnetic and optical devices, and pharmaceuticals, among others. This Field Guide examines the basic phenomena and techniques of growing bulk single crystals from solution, melt, and vapours.

The polarization of light is one of the most remarkable phenomena in nature and has led to numerous discoveries and applications. The main objective of this guide is to provide an introduction to the developments in polarized light that have taken place over the past half-century, and present the salient topics of the subject.

Describes the many different types of optical fibres and their properties, and presents in a compact form their relevant physical foundations. Both passive and active (amplifying) fibres are discussed, and an overview on fibre nonlinearities and the application of active fibres in amplifiers and lasers is included.

Starting with traditional illumination in imaging systems, this title follows the advances in computer-aided design of high efficiency nonimaging illumination optics, along with the modern source models that support these techniques. It includes sections on the illumination of visual displays and some topics on architectural illumination.

Offers an overview on the types of lasers and their key properties as well as an introduction into the physical and technological aspects of lasers. Apart from describing the basic principles, this title discusses the different properties of laser crystals, the impact of thermal effects on laser performance, and methods of wavelength tuning.

Until the discovery of the Islands in 1535, the flora and fauna of the Galapagos evolved in isolation, producing strange and marvellous island species. Many people visit the islands to see the unique wildlife. This book provides a comprehensive guide to the terrestrial vertebrates on Galapagos.
