| 摘 要： | 衍射光栅是一种非常精密的光学元件。它们通常是用金刚石刀具刻划的。为了使光栅有较高的衍射效率,金刚石刻划刀应有精确的角度。正确选择金刚石晶格的方向对提高刀具的寿命非常重要。光栅刻划刀刀刃的粗糙度好于8nmRa.

| Abstract: | Diffraction gratings are very accurate optical elements,which are ruled by diamond tools usualy. In order to get higher diffraction efficiency of gratings, the angles of ruling tools must be very accurate. Chosing the direction of diamond lattice is very important for raising service life of' the tools. The smooth finish at the edge of the tools is better than & nmRa. |
