Lens cement failure

Wed, 2012-03-14 16:37 - bouabidz

Hello all, I am having problem with one of our lens doublets getting decemented. we have been cementing this lens for many years and we did not do anything different. Recentely we start seeing this lens decementing. we use NO61 and NO65 (UV curing). Any help of how to prevent this problem from happening again will be very much appreciated.

Thank you,
