The compound eye of an insect like the housefly is effectively a bound of tapered fiber optical filaments . 昆虫（如家蝇）的复眼实际上是一束丝状的锥形光学纤维丝束。
The index of refraction of most of the common glasses used in optical instruments lies between 1. 46 and 1. 96 . 光学仪器中最常用的玻璃其折射率多在146到196之间。
Here the interference pattern is established between an optical flat and the polished specimen surface of the glass . 在光学平板玻璃和磨光试样表面之间建立起干涉图样。
An optical shop, in the business of making lenses, will have a set of precision spherical test plates or gauges . 制造透镜的光学车间，应当有一套精确的球面测试板即球面规。
Most commonly measured optical quantities in the atmosphere are heavily dominated by portion of the size range . 大气中普通测量的大多数光学量都明显地由粒子大小范围的某一段来决定。
The basic optical requirement is a fine pencil or thin ribbon of highly collimated, monochromatic, polarized light . 基本的光学要求是要有一个高度准直的单色偏振光的细光束或薄光带。
