| Abstract | ||
| In this paper the manufacturing of diffraction grating is done using (dichromate gelatin) which is sensitive to wavelength 532.5nm, by using two ways, the first one is the (in-line) way and the other is the (off-axis) way. The effect of both concentration of (dichromate) and the interference angle between the body wave and reference beam on the orders of diffraction and the number of fringes was studied. Where the second method with increase the interference angle is better than from the first one because clarity and increase the number of fringes. | ||
