For more than 400 years, optical glass has provided mankind with a window into both the hidden microcosm and vast outer cosmos of the known universe, transforming philosophy, science, and engineering through its visage and, thus, shaping modern civilization. Its high transmittance, homogeneity, and precisely defined light refraction properties are the preconditions for highly resolved true-color imaging, making it an intrinsic component of technology in general. From consumer products, such as cameras and binoculars, to microscopes and telescopes the most essential tools of research in many fields the role of optical glass is integral to the very foundations of modern science and industry.
In contrast to its fundamental importance, there is often a lack of knowledge regarding the properties of optical glass by engineers and designers, causing misunderstandings in purchasing and fabrication, and ultimately limiting the potential and application of this dynamic material. This book will serve as an invaluable resource of technical information, including the index of refraction and its dependence on wavelength (dispersion), optical homogeneity and transmittance (presented together with restrictions imposed by the manufacturing processes and chemical resistance), as well as mechanical, thermal, and environmental properties. Measurement methods with their achievable accuracy are given, along with a wide scope of overview diagrams illustrating properties and main uses, as well as diagrams ranking optical glass types with respect to their properties. The wide scope and lucid organization of this volume will prove to be highly valuable across a wide range of design, engineering, and purchasing applications within the many fields dependent on this incredible material.
About the Author
Peter Hartmann received his Doctorate in Physics in 1984 from the University of Mainz, Germany. His thesis was on scintillation glasses made at the nuclear physics department of the Max-Planck-Institute for Chemistry in collaboration with Schott Glaswerke. In 1985, after serving as head of a geometrical metrology group in the automotive industry, Dr. Hartmann joined the optics division of Schott. Since then, he has been responsible for quality assurance, metrology development, and advising customers on optical glasses and the zero-expansion glass ceramic ZERODUR®. He has been responsible for projects such as extremely high-quality optical glass for i-line microlithography, and mirror blanks for large astronomical telescopes (Keck I and II, CHANDRA, ESO-VLT, GRANTECAN, and several 4-m telescopes). Since 2007, he has been the Director of Marketing and Customer Relations of Advanced Optics at SCHOTT AG.
Dr. Hartmann served on the Board of Directors of SPIE from 2011 to 2013 and is active in international standardization as a convener of the ISO working group for optical materials. He is a member of the board of the Optics and Photonics Cluster OPTENCE, Hesse/Rhineland-Palatinate, Germany and of the Board of Trustees of the Max-Planck-Institute for Astronomy, Heidelberg, Germany. He is Fellow of SPIE.
