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.
