X射線準直

X-ray collimator

X射線準直器是基于微通道板技術開發的一款新品，可對2-50KeV的X射線進行光學準直，廣泛應用于深空探測、航天導航、核爆診斷、醫療、安檢、熒光分析等領域。X射線準直器是一種高鉛玻璃材質的薄片，內部包含數百萬個微米級尺寸的準直通道，其基于角度靈敏性原理，利用準直通道內壁高含鉛量和高粗糙度實現對雜散X射線的吸收，利用準直通道的高精度指向實現對X射線的光學準直。與傳統的金屬型X射線準直器相比，微通道板型X射線準直器的分辨率更高，更加輕量化，并且可以實現更大面積陣列的拼接，因此具有更加廣泛的應用前景。

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.

技術參數

產品特點

高分辨率

金屬型X射線準直器主要通過金屬片機加工、對插、激光焊接和 點膠等工藝制得，其準直孔的最小極限尺寸在毫米量級。隨著后端探測器的分辨率越來越高，要求準直器準直孔的尺寸越來越小。 微通道板型X射線準直器的準直孔尺寸為微米量級，能更好地實 現高分辨率。

大面積輕量化

微通道板型X射線準直器體積小、重量輕，可通過陣列式的拼接實現非常大的面積，并且在相同面積的同類產品中重量最輕。

高準直精度

微通道板型X射線準直器通過精密光纖拉制、熔合等工藝制成， 準直孔整體指向精度高，對X射線的角度響應曲線與曲線高 度吻合，準直精度高。
