摘　　要：真空环境下大口径光学元件的装夹采用传统有机物无应力装夹方式会带来有机污染等各种问题。设计了一种大口径平面光学元件的夹具和装夹方案,利用金属结构直接装夹大口径平面光学元件,可在降低金属装夹框表面加工精度和光学元件处于任意倾斜角度等情况下,不产生光学元件装夹应力,同时避免了传统有机物无应力装夹而带来的有机污染。可广泛应用于大口径平面光学元件在光学工程、光学实验装置中的装夹。Large aperture optical element clamping generally use the traditional organic stress- free clamping.In vacuum environment, the clamping will bring about various problems such as the organic pollution. A fixture scheme and the corresponding fixture have been designed for large plane optical element. The scheme uses the metal structure for clamping optical element directly, reduces surface machining accuracy of metal frame,achieves stress- free clamping and avoids organic pollution caused by traditional way with the optical element working at any angles. This scheme can be widely used in the large aperture optical elements clamping in optical engineering and optical experimental device.
