CONTAX Carl Zeiss Mirotar 500mm f/8.0 T* 前鏡組脫膠/離膠重新黏合 Re-cementing for front lens elements separation

這支CONTAX 500/8反射鏡的前鏡組出現了脫膠/離膠的問題
此鏡組是由一片大的透鏡(#2)、一片小透鏡(#3) 以及一個反射鏡面(#1) 組成，我收到鏡頭的時候，#1和#3都偏向同一個方向位移了。
取出整組鏡組，把三片鏡片都分開，仔細將殘膠清潔乾淨，在依序將三鏡片精準的重新黏合在一起，讓鏡頭恢復原狀！

This Contax 500/8 mirror lens got a separation problem on its front group.
The component of the front group is a large lens (#2), a small lens (#3) and a mirror lens surface (#1) which all cemented together. When I received the lens, I saw the position of #1 & #3 shifted.
I took out the front group and tried to separate the 3 lenses and cleaned the residual glue, then re-cemented them together precisely to restore the lens to its original condition!
