Popov’s book Aspherical Surfaces in Astronomical Optics is a unique study that immerses the reader in the exciting world of optics and astronomy. This edition will be a real find for students, graduate students, researchers and anyone interested in modern methods of optical design and their application in astronomy. In his book, Popov reveals the complex concepts of aspherical surfaces that play a key role in the creation of high-quality optical systems. Aspherical elements, unlike traditional spherical ones, can significantly improve the characteristics of optics, reducing aberrations and increasing the luminous intensity. This is especially true in astronomy, where the accuracy and quality of the image are crucial for observations of distant objects. The author explains how aspherical surfaces can be used to create more efficient telescopes and other optical instruments, which opens up new horizons for astronomical research. The book will be of interest not only to specialists in the field of optics, but also to those who are fond of astronomy and want to understand more deeply how modern telescopes and other optical devices work. Students of technical and natural sciences, as well as lovers of astronomy, will find in it a lot of useful information and practical examples. Popov uses accessible language and visual illustrations, which makes the material understandable even for those who are just beginning to get acquainted with this topic. The topics raised in the book concern not only the technical aspects of optics design, but also philosophical issues related to the perception of the cosmos. How does technology change our view of the universe? How do aspherical surfaces help us better see and understand the world around us? Popov raises these questions and invites the reader to think about how science and technology affect our perception of reality. The author's style is distinguished by clarity and consistency. Popov, as an experienced specialist in the field of optics, is able to explain complex things in simple language, which makes his books available to a wide audience. His previous works, such as "Optical Systems and Their Applications" and "Modern Methods of Optics Design", have also gained recognition and have become major textbooks for students and professionals. In Aspherical Surfaces in Astronomical Optics, he continues this tradition by offering readers not only theoretical knowledge but also practical recommendations. The book will be an excellent addition to the library of anyone interested in science, technology and astronomy. It can be useful for both professionals and amateurs seeking to expand their horizons. Readers who seek information about modern optical systems, astronomical observations, and design methods will find in this edition many valuable ideas and inspirations. In conclusion, “Aspherical Surfaces in Astronomical Optics” is not just a textbook, but a real encyclopedia of knowledge that will help readers better understand how optical systems work and how they affect our perception of the cosmos. This book will be a reliable companion for anyone who wants to deepen their knowledge in the field of astronomy and optics, and, of course, deserves attention.
