RT 設計了一個光學系統(tǒng) 其中有一個光學元件的折射率設的是Gradient 但同時想要這個元件的面型變成 Zern Frn Sag。請問是不是要加相位板？怎么設置？ khtYn.eaL  
感謝走過路過的大俠的賜教 O%?d0K  

there is an NS object biconic Zernike which make use of Standard sag and you could assign it to be gradient lens. this is the closet I am aware of, but since you are looking into phase plate, not sure if Zernike Standard Sag would be much use to you. Some conversion mught be required.....

Thanks for your help and instruction! I'll try to do that follow your guide^^
