Description

一种光学反射镜夹持装置
技术领域
本发明属于光学元器件领域,具体涉及一种光学反射镜的夹持装置。
背景技术
现有的光学元器件领域中,对各种光学镜片如反射镜等的应用极其频繁。尤其在光学测量类仪器里,随着光学测量体系的日益先进,对光学测量数据的精度日益提高,对反射镜的要求也就越来越高。而反射镜的镜面平直度要求则是保证测量光束稳定乃至光学测结果精确与否的重要因素之一,现有的各种光学反射镜的加工技术已经可以保证制造出符合要求的镜片,但是在进行反射镜夹持时,一旦夹持不当,反射镜仍然会不可避免的发生翘曲变形,导致经其镜面折射后的测量光束的光路发生偏差,从而对测量结果的准确性造成了严重影响。此外,当测量器件处于频繁振动等测量状况不佳的场合时,如果反射镜夹持不够牢靠,其镜片往往就会反生松动移位甚至从其固定支架上掉路, 引发光路系统故障,继而极大的影响了测量效率。
发明内容
本发明的目的是提供一种光学反射镜的夹持装置,能够达到可靠夹持反射镜的目的。
为实现上述目的,本发明采用了以下技术方案:一种反射镜的夹持装置,包括用于固定反射镜的支架,支架上设有限制反射镜沿其镜面的平行方向移动的限位部,所述支架上设置有约束反射镜边缘处位置的夹卡,与夹卡相对应的支架上还设有支撑部,所述支撑部和夹卡构成限制反射镜沿镜面垂直方向移动的限位配合。
本发明的有益效果在于:当采用上述结构以后,通过限制反光镜在空间上的平行和垂直运动来达到限制其空间位移的作用,以实现本发明的可靠夹持并固定反射镜的目的。
