Intorduction To Light Microsco

This book offers a beginner’s guide to using light microscopes. It begins with a brief introduction to the physics of optics, which will give the reader a basic grasp of the behaviors of light. In turn, each part of the microscope is explained using clear and simple English, together withdetailed photographs and diagrams. The reader will learn the function, care and correct use of each part. A troubleshooting section also helps resolve some of the most common issues encountered in light microscopy. Most people have a general idea of how to use a microscope, but many never get the full benefit, because they receive no training. With easy-to-follow steps and detailed images, this guide will help everyone achieve the best results, and be confident using their microscope. This book is intended for anyone using a light microscope, such as university students, people in lab environments, hobbyists, educators who teach science to young children, and anyone with a general interest in these valuable tools.

This book provides detailed and fully illustrated advice on choosing and using the appropriate type of light microscope for a particular application. The low-power stereomicroscope is described, and the many different types of condensers, objectives and eyepieces required for the high-power compound microscope are explained in detail. The book also describes the correct care and use of the microscope in order to achieve the best possible image, and provides a checklist to aid in the diagnosis and correction of problems. Practical step-by-step guidance ensures that the reader always obtains a clear image, Introduction to Light Microscopy is therefore an essential guide for amateur and professional users of the light microscope in all areas of science.

Presents a fully updated, self-contained textbook covering the core theory and practice of both classical and modern optical microscopy techniques.

Many people look upon a microscope as a mere instrument(l); to them microscopy is instrumentation. Other people consider a microscope to be simply an aid to the eye; to them microscopy is primarily an expan sion of macroscopy. In actuality, microscopy is both objective and sub jective; it is seeing through an instrument by means of the eye, and more importantly, the brain. The function of the brain is to interpret the eye's image in terms of the object's structure. Thought and experience are required to distinguish structure from artifact. It is said that Galileo (1564-1642) had his associates first look through his telescope microscope at very familiar objects to convince them that the image was a true representation of the object. Then he would have them proceed to hitherto unknown worlds too far or too small to be seen with the un aided eye. Since Galileo's time, light microscopes have been improved so much that performance is now very close to theoretical limits. Electron microscopes have been developed in the last four decades to exhibit thousands of times the resolving power of the light microscope. Through the news media everyone is made aware of the marvelous microscopical accomplishments in imagery. However, little or no hint is given as to what parts of the image are derived from the specimen itself and what parts are from the instrumentation, to say nothing of the changes made during preparation of the specimen.

Following three printings of the First Edition (1978), the publisher has asked for a Second Edition to bring the contents up to date. In doing so the authors aim to show how the newer microscopies are related to the older types with respect to theoretical resolving power (what you pay for) and resolution (what you get). The book is an introduction to students, technicians, technologists, and scientists in biology, medicine, science, and engineering. It should be useful in academic and industrial research, consulting, and forensics; how ever, the book is not intended to be encyclopedic. The authors are greatly indebted to the College of Textiles of North Carolina State University at Raleigh for support from the administration there for typing, word processing, stationery, mailing, drafting diagrams, and general assistance. We personally thank Joann Fish for word process ing, Teresa M. Langley and Grace Parnell for typing services, Mark Bowen for drawing graphs and diagrams, Chuck Gardner for photographic ser vices, Deepak Bhattavahalli for his work with the proofs, and all the other people who have given us their assistance.
