上叉

Before the measurement the cross hair is to be placed on the monitor sharply.

测量之前，十字叉丝在监视器上清晰显现。

The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.

一种离轴抛物面镜点聚焦能力测定装置和测定方法，测定装置的构成包括：一台He-Ne激光器，沿该He-Ne激光出射激光束方向依次设置扩束器、软边光阑和待测的离轴抛物面镜，在该离轴抛物面镜的反射光束方向依次设置标准叉丝和显微物镜，该显微物镜位于所述的离轴抛物面镜的焦点，所述的焦点成像于面阵CCD上，该面阵CCD的输出端接计算机，所述的离轴抛物面镜固定在一五维电动调整架上。
