The focal length is a very important indicator of the grid

A few days ago, a customer in Malaysia purchased our grid through a freight forwarding company in Guangdong. What the customer wants is 15*18 and 11*13 convergence grids with a focal length of 1 meter. Before confirming the purchase, we talked about the focal length for a long time. At the beginning, the customer did not give the focal length data, so I asked the customer if they want parallel grids? The client said that the hospital didn’t say what it wanted, but the doctor didn’t understand it very well. After repeated confirmation from the client and the hospital, it was determined that the convergent grid was required with a focal length of 1 meter, which was finally confirmed.
Speaking of grids, we have to talk about the problem of convergence grids or parallel grids. Parallel grids have no focal length. They are generally used on old-fashioned X-ray machines. Now they are rarely used and need to be customized. Generally, the waiting time is relatively long.
Convergence grids are the mainstream grids used today. When customers buy, we need to ask about the focal length in addition to the customer’s size, grid density, and grid ratio. Because the role of the wire grid is to filter out the scattered rays, making the image clearer. If the selected focal length is not suitable, the effect will not be achieved, so the focal length of the grid is a very important indicator. Be clear when buying.
