This book is an introduction to optics and optical fabrication that provides technicians with simple explanations supported by illustrations and diagrams. Detailed examples and calculations are also included. The behaviour and performance of optical elements as individual components and as members of complete systems are discussed and evaluated. Further topics include the manufacturing, testing, and mounting of optical elements; two-element systems; optical coatings; and aberrations.

The author has expanded the information found in his practical 1995 tutorial. Achromats are covered in more detail, with an updated discussion of beam expanders. Ball lens, gradient optics, and three mirror configurations have been added to the chapter on Special Optical Surfaces and Components. A new section discusses wave aberrations, with a comparison of the spherical aberration to the Seidel coefficient. A new chapter on thermal effects examines the design of athermats-lenses that compensate for undesired results caused by temperature excursions. Also new is an application and summary chapter, Design Examples. As diamond turning is especially suitable for producing aspheres and diffractive infrared elements, a chapter has been added describing this method of manufacture.
