摘要： A combined retardation optical device includes a first retardation optical plate and a second retardation optical plate. The second retardation optical plate contains a flat portion and a multi-step portion. This multi-step portion has several step-like flat surfaces with predetermined heights. The flat portion contacts with the first retardation optical plate. Both the first retardation optical device and the second retardation optical plate are made by birefringent materials. This invention is easy to switch to different retardation condition for observation. Plus, there is no need to adjust or replace any element.
摘要翻译：组合延迟光学装置包括第一延迟光学板和第二延迟光学板。第二延迟光学板包括平坦部分和多台阶部分。该多步部分具有几个具有预定高度的阶梯状平坦表面。平坦部分与第一延迟光学板接触。第一延迟光学器件和第二延迟光学板都由双折射材料制成。本发明易于切换到不同的延迟条件进行观察。此外，没有必要调整或更换任何元素。
