商品描述
Anyone who has looked through binoculars, a telescope or microscope has used an eyepiece. Telescope Eyepieces: Optical Theory and Design explores the wide range of eyepiece designs. It introduces optics theory progressively to build understanding of how lenses control light in an optical system generally and in eyepieces specifically, linking optics fundamentals, design evolution and the implications for image quality. The book presents a logical narrative starting with Snell's law of refraction at a flat surface, progressing to paraxial and real rays at spherical and aspherical surfaces, lenses and thin-lens systems. It demystifies the origin of aberrations by considering wavefront deviations, all brought to life in the context of the familiar eyepiece. Principles are explored both descriptively and mathematically, and carefully interpreted so the reader is not swamped by a sea of equations. The book contains many diagrams of ray tracing results to illustrate optical principles and the consequences of design choices, enabling the reader to visualise their impact on image quality and to cut through the puffery that is sometimes found in the marketing of telescope eyepieces. The book bridges the gap between introductory books and expert-level optical design texts, written jointly for an astronomy readership and for physics and optical-design students.
Key Features:
- Develops an understanding of optics by focusing on the design variations of a particular multi-lens system - the eyepiece - which readers will have used when looking through binoculars, telescopes and microscopes.
- Combines descriptions and interpretations of theory with many illustrative visualisations of eyepiece designs to help the reader develop an intuitive understanding of optics and aberrations in the familiar context of eyepieces.
- Written by a Professor of Astrophysics with experience as both an amateur and professional observer using telescopes at observatories around the world.
商品描述(中文翻譯)
任何曾經透過雙筒望遠鏡、望遠鏡或顯微鏡觀察的人，都使用過目鏡。《望遠鏡目鏡：光學理論與設計》探討了各種目鏡設計。它逐步介紹光學理論，以建立對透鏡如何在光學系統中控制光線的理解，特別是在目鏡中，並將光學基礎、設計演變及其對影像品質的影響聯繫起來。這本書以邏輯性的敘述開始，從斯涅爾定律（Snell's law）在平面上的折射開始，逐步進入球面和非球面上的近軸光線和實際光線、透鏡及薄透鏡系統。它通過考慮波前偏差來揭示像差的起源，所有這些都在熟悉的目鏡背景下生動呈現。原則以描述性和數學性方式進行探討，並仔細解釋，以免讀者被大量方程式淹沒。書中包含許多光線追蹤結果的圖示，以說明光學原則及設計選擇的後果，使讀者能夠視覺化其對影像品質的影響，並能穿透有時在望遠鏡目鏡行銷中出現的誇大之詞。這本書填補了入門書籍與專家級光學設計文本之間的空白，專為天文學讀者及物理和光學設計學生共同撰寫。
主要特點：
- 通過專注於特定多透鏡系統（目鏡）的設計變化，發展對光學的理解，讀者在使用雙筒望遠鏡、望遠鏡和顯微鏡時都會用到這些目鏡。
- 將理論的描述和解釋與許多目鏡設計的插圖視覺化相結合，幫助讀者在熟悉的目鏡背景下發展對光學和像差的直觀理解。
- 由一位擁有天體物理學教授職位的作者撰寫，他在世界各地的天文台使用望遠鏡進行業餘和專業觀測方面擁有經驗。
