A holographic grating was fabricated on a spherical surface using 5 axis ultrahigh precision machine tool. The fabrication of holographic grating have been carreid out with burnishing method. but it was not always possible to obtain deep blazed cross section or curved grooves. The authors here adopt ultraprecision cutting method with V-shaed single crystalline diamond cutting tool to overcome those limitations. A sample grating on a SR1000 sphere was successfully fabricated by this method.
