“binoculars”的概念、定义、习题解题方法及翻译-物理辞典

单词	binoculars
释义	binoculars Any optical instrument designed to serve both the observer's eyes at once. Binocular field glasses consist of two refracting astronomical telescopes inside each of which is a pair of prisms to increase the effective length and produce an upright image. Simpler binoculars, such as opera glasses , consist of two Galilean telescopes which produce upright images without prisms. Commonly, binoculars are specified by a pair of numbers, such as 10 × 50. The first number indicates the angular magnification produced. The second is the diameter of the objective lens in millimetres, and indicates the amount of light gathered by the instrument. Binocular microscopes are used in biology and surgery to enable the observer to obtain a stereoscopic view of small objects or parts
