lens of extreme aperture 中文意思是什麼
lens of extreme aperture
解釋
臨界孔徑物鏡-
Generally, the gravity introduced deformation of an optical lens with smaller aperture ( < ( 100mm ) within visible band is about ( / 20 even less than this value. for general optical lens, this error level can be entirely neglected. but for the high - accuracy optical system within extreme ultraviolet band, the error caused by gravity deformation will lead to imaging quality degradation
本文較為系統地介紹了光學鏡頭的裝配與調校方法,一般地講,在可見波段內,光學鏡片口徑較小( < 100mm )時,重力引起的變形一般/ 20左右甚至更小,對於一般的光學鏡頭這樣量級的誤差完全可以忽略,但在極紫外短波長的高精度光學系統中重力變形帶來的誤差會使光學系統成像質量下降。
