成品鏡頭的像面重影問題!

各位大俠,問下重影出現的根本原因是什么,我能確定是膠合件出問題的多,但是膠合件沒有涂墨,但是重影很嚴重,求解釋下,非常感謝!

上圖看看

Provide more information would be useful, but it sounds like that this effect may not be minimized during the design processes if all the lenses are properly coated.

2樓的意思是有可能是鬼像,確認鍍膜是否達到要求。

Yes, it's just a thought that it might be 鬼像. When I said if there is no problem with the coating I meant that if the coating was done and performing as it was designated to then the coating is already doing its best. If so, then the design concept may not have minimized this effect.   Like the other reply, having more information would be helpful.

膠合件膠合是否正確

膠合件測了,中心厚度沒有問題,已經膠合了沒辦法拆開測

感謝您的回答,這個問題還沒有解決,問了好多設計人員,也沒有給出明確的答復,期待后來者呀

膠合件沒有涂墨,做替換實驗發(fā)現膠合件影響的呀

Do you have a photo of these multiple image effect? f<uLbJ6

If you think its the doublet that causes this problem then check the ray tracing for ghost image analysis to confirm it's not a design issue but rather a fabrication issue. at least it help to narrow down it's design or the manufacturing problem.

嗯,今天問了一個工程師,說是鏡片加工本身參數出錯,不是鍍膜的問題,還是謝謝您的幫助!TKS

重影就是不清晰了,分辨率很低。
