Product Details

Description
Radiation from different areas of the focal spot will cause a periodic blurring of the pattern due to penumbra effects. Knowledge of the geometric factors, and the distance from the center of the pattern to the region where blurring occurs, will permit the calculation of the focal spot size with the same accuracy as measurements made with a pinhole camera.
075092000 - High-Precision Star X-Ray Test Pattern, 55 mm Ø; For measuring focal spots from 1 mm and up. Has four 45° sectors with a 2° angle of a single line within a sector. Lead-foil thickness: 0.05 mm.
