Further, described seal groove is rectangle annular groove; Described O-ring seal is rectangular ring.Adopt this structure, after installation, circumference mutually can be reduced and loosen.
Further, described press box offers stepped hole on its surface towards underframe side, is provided with sealing frame in this stepped hole.Adopt this structure, in clamping process, the another side of optical element is also provided with flexible sealing frame, and the two sides of optical element all have elastic buffer effect, and contact is better, also can avoid breakage, can realize vacuum seal performance.
Further, described stepped hole is rectangular opening, and described sealing frame is rectangle moulding.Adopt this structure, can match with seal groove, after installing simultaneously, circumference mutually can be reduced and loosen.
Further, described sealing frame adopts polytetrafluoroethylmaterial material.Adopt this structure, this sealing frame is the teflon moulding with flatness and purity requirements, and object is optical element is not directly contacted with mechanical mechanism.
Further, described underframe is rectangle deckle board, and described underframe adopts aluminum alloy material, and its structure is simple, weight reduction.
Further, each described tie down screw rectangular annular distribution on described underframe.
The beneficial effects of the utility model are: the utility model structure is simple, and clamping device good airproof performance, is applicable to the clamping of the optical element had higher requirements for vacuum leakproofness.Meanwhile, fastening means have employed novel structure, control better, the requirement of system of optical elements to cleanliness factor can be better met, and improve cleanliness factor and the vacuum seal performance of clamping process framework to cleanliness factor.
