Grid distortion test targets (Grids)
Grid distortion test targets (Grids)
Product details
The grid array is located at50mm×50mm，1.5mmOn a thick glass substrate (made by vacuum sputtering low reflectivity chromium on the glass substrate),100µmThe250 µmThe500 µmThe1000µmand2000µmGrid spacing,25×25Array.
Grid distribution is used to determine the distortion of imaging systems. In an ideal situation, the horizontal and vertical lines of the grid are perpendicular, and distorted images will appear distorted online, which can be used to correct distortions.
