With the recent availability of front side hard coat 1.74, i have been able to process rx in house for ecp's who prefer not to sell w/ar. I know reflectance can be an issue but the topic of this thread is one of applying backside hard coat.
I am using an ultraoptics mr-iii. Pre coat lenses check great power is dead on. Post coat can see the optics have been affected. Some lenes will change from a .12 to as much as a .25. Obvioulsy the cure and heat is affecting center. I have increased the finish thickness from 1.5 to 1.8 but the goal is to be close to 1.0 with great optics.
So my question is..any suggested means to adjust coating cycle or methods?
