快速設(shè)計一個30倍的變焦鏡頭:SYNOPSYS 光學(xué)設(shè)計軟件
."`||@| 第38課展示了如何設(shè)計8X變焦鏡頭。現(xiàn)在我們做一個復(fù)雜的設(shè)計,以30X變焦為目標(biāo),來設(shè)計一款變焦鏡頭。 [C@Ro,mI 設(shè)計要求如下: bb$1zSA 1. 變焦30倍 2. 半視場角14° 3. 最后一面的半孔徑為3mm 4. 使用11個鏡片 5. 四組鏡片,其中兩組是用來變焦 6. 像高5mm 7. 后焦距20mm 8. 總長600mm 9.物距從無窮遠到5m范圍內(nèi)對焦清晰 nPH\Lra ZSEARCH輸入如下: (N5"'`NZA LOG ! to keep track of things later ON 98 {~#d_!( TIME ! to see how long this run took CORE 14 )))AxgM ZSEARCH 3 QUIET ! save results in library location 3 Fzz9BEw(i }6*JX\'q SYSTEM u\km_e ID ZSEARCH TEST ](`:<>c OBB 0 14 3 ! infinite object, 14 degrees semi field, 2.85 mm semi -?Cu-' ! aperture.
