X射线准直

X-ray collimator

X射线准直器是基于微通道板技术开发的一款新品，可对2-50KeV的X射线进行光学准直，广泛应用于深空探测、航天导航、核爆诊断、医疗、安检、荧光分析等领域。X射线准直器是一种高铅玻璃材质的薄片，内部包含数百万个微米级尺寸的准直通道，其基于角度灵敏性原理，利用准直通道内壁高含铅量和高粗糙度实现对杂散X射线的吸收，利用准直通道的高精度指向实现对X射线的光学准直。与传统的金属型X射线准直器相比，微通道板型X射线准直器的分辨率更高，更加轻量化，并且可以实现更大面积阵列的拼接，因此具有更加广泛的应用前景。

X-ray collimator is a new product developed based on MCP technology, which can  perform optical collimation of 2-50kev X-ray, and is widely used in deep space detection, space navigation, nuclear explosion diagnosis, medical treatment, security inspection,   fluorescence analysis and other fields. X-ray collimator is a kind of high lead glass flakes, interior contains millions of micron-sized collimating channels. The collimator utilizes the principle of angle sensitivity, using collimating channel wall high lead content and high roughness to absorb stray X-ray, the optical alignment of X-ray is realized by high-precision pointing of collimating channels. Compared with the traditional metallic X-ray collimator, the MCP type X-ray collimator has a higher resolution, lighter weight, and a larger area of array splicing, so it has a wider application prospect.

技术参数

产品特点

高分辨率

金属型X射线准直器主要通过金属片机加工、对插、激光焊接和 点胶等工艺制得，其准直孔的最小极限尺寸在毫米量级。随着后端探测器的分辨率越来越高，要求准直器准直孔的尺寸越来越小。 微通道板型X射线准直器的准直孔尺寸为微米量级，能更好地实 现高分辨率。

大面积轻量化

微通道板型X射线准直器体积小、重量轻，可通过阵列式的拼接实现非常大的面积，并且在相同面积的同类产品中重量最轻。

高准直精度

微通道板型X射线准直器通过精密光纤拉制、熔合等工艺制成， 准直孔整体指向精度高，对X射线的角度响应曲线与曲线高 度吻合，准直精度高。
