A company inquired about X-ray collimator for research and development, and asked the customer what kind of X-ray machine is the X-ray collimator used? How many KV? The customer said that they are now looking for X-ray collimator for R&D. Material development is now in progress. Please give them some relevant information and quotation for the X-ray collimator. It is still not sure what kind of X-ray collimator you want. The company just told him this morning, and he is not very good about other information for the time being. Clearly, first give him some X-ray collimator materials for reference. It is recommended that customers use the NK-202C X-ray collimator, which is mainly used for fixed X-ray machines, and is mainly matched with 150 KV X-ray tubes.
