X-ray Collimator

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.

High Resolution

• Metallic X-ray collimators are primarily fabricated through processes like metal machining, threading, laser welding, and gluing. The minimum limit size of the collimation hole is at the millimeter level. With the increasing resolution of back end detectors, there is a requirement for smaller collimation hole sizes. Microchannel plate X-ray collimators have hole sizes on the micrometer scale, enabling better achievement of high resolution.

Large Area and Light Weighting

• Microchannel plate X-ray collimators have small volume and light weight. They can be assembled in an array fashion to achieve a very large area, and they are the lightest among similar products with the same area.

High Collimation Accuracy

• Microchannel plate X-ray collimators are fabricated through processes such as precision fiber drawing and fusion. They exhibit high overall collimation accuracy, with the angular response curve matching the ideal curve very closely, resulting in high collimation precision.
