在本課程中,我們將從相同的初始結(jié)構(gòu)開始 - 但在這種情況下,我們希望四個(gè)視場都能實(shí)現(xiàn)高M(jìn)TF,并將目錄玻璃類型替換為前一課程的玻璃模型。 為了做到這一點(diǎn),我們將使用自動(dòng)實(shí)際玻璃插入程序ARGLASS

ARGLASS功能允許您過濾一些選項(xiàng),這過濾項(xiàng)會(huì)影響程序選擇玻璃。 例如,您可能只需要便宜的玻璃或耐酸性良好的玻璃。 在本練習(xí)中,我們只想使用具有良好環(huán)境特性的類型。 這是選擇的內(nèi)容:

我們建議您自己運(yùn)行此練習(xí)。嘗試更改一些視場權(quán)重或孔徑權(quán)重,然后再次運(yùn)行。結(jié)果對(duì)這些變化非常敏感,當(dāng)你設(shè)計(jì)自己的鏡片時(shí),你需要了解哪些控制有效,哪些控制無效。
(該程序以非零光焦度開始,根據(jù)其規(guī)則分配,并發(fā)現(xiàn)更多設(shè)計(jì)。)我們嘗試了解這個(gè)問題,并得到了更好的解決方案。調(diào)整輸入變量以查看發(fā)生的情況。
