The grid density of the grid and the active grid are respectively

What are the grid densities of short grids and active grids? Let’s first explain to you what grid density is. Line rate: The number of lead bars within a unit distance, expressed in N. Our company often sells ordinary grids, grid density: 40L/CM.
High grid density: from 60 or 70 lines/excellent, to high density (85 lines/inch), ultra-high density (103 lines/inch), invisible lines (105 lines/inch), super invisible lines (170 or 200) Line/inch)
So how to choose a grid? The first choice is to clarify which device is equipped with the grid, such as a cassette, an IP board or a flat panel? What is the size of the board? For general cassettes or wire grids used on IP boards, you can choose conventional size: 15*18, grid ratio: 10:1, grid density: 40L/CM. The grid on the flat panel detector needs to be customized according to the brand and model of the flat panel.
