Parameters of fine X-ray grid

Fine X-ray grid board appearance for a 4~8MM thick plate.The internal structure is made of many thin strips of lead arranged to focus. The two lead strips are positioned and cemented together with a substance that penetrates x-rays.
X ray grid fillers can be wood, paper or aluminum sheets.Finally up and down with thin aluminum packaging, forming a screen grid version. From the view of the section, the direction of arrangement of the filter plate lead will converge to a point. From the whole grid board, there is a convergence line.
Parameters of fine X ray grid
According to this construction, the fine X-ray grid parameters of different specifications are as follows:
1. Focal length: the vertical distance from the lead convergence line to the grid plate surface.
2. Grid ratio: also known as grid ratio, is the ratio of lead height to lead clearance.
3. Grid density: the number of lead bars within the range of unit distance.
Newheek fine X-ray grid griders usually have 8:1, 10:1, 12:1 and a few 6:1. Gate densities are usually 80-85 lines/inch and 100-103 lines/inch. The outer dimensions of the filter bars range from 6 x 8 to 15 x 37.
Newheek fine X-ray grid can be customized.
