Then doing a recement. Let me explain, I have a Summilux element with fungus in between the two cemented elements. Its an early lens from 1960. In Thomas Tomosys Leica Guide he says that if it is an early lens then its cemented with Canada Balsam and that its easy to just heat it up to 150f and separate the element. Then clean it and then re-cement with Norland Optical Adhesive and then harden with a UV light. I don’t have optical adhesive or a UV light... I will have to order it. Has anyone had any experience with separating and cleaning Leica cemented elements? Please advise. Thanks
