The Seya-Namioka concave holographic grating itself is a monochromator system, which combines the functions of collimation, diffraction and focusing through only one grating. The entry and exit positions of the seam are fixed, and the wavelength scanning process is completed through the rotation of the grating. Through computer optimization design, this grating can be made to have small astigmatism and coma.
