How many focal lengths should I choose to buy an X-ray grid?

The focal length of the X-ray grid is actually the vertical distance between the lead bars converge on the surface of the grid. It is represented by F. Our X-ray grids are all 0.7-1.8m optional, and the common ones are 100cm and 180cm. X The short focal length of the ray grid can replace the long focal length. There are many sizes of X-ray grids, but generally only 15*18 and 18*18 are commonly used. If you buy an X-ray grid, you must remember to ask, size, focal length, grid ratio and grid density, these are the most important parameters for comparison. If you have something you don’t understand, you are also welcome to consult us and we will answer you one by one.
