    Does anyone know the sag of the Pentax AF Mini 6Base in a 1.50 plastic?

    Harry, Just a thought.

    You can rearrange the back vertex formula to solve for D1 if you know D2, power, and thickness. Then find the sag of D1

    That's not a bad idea but the optics aren't clean enough on the semi finished lenses to get an accurate read. I'm gettign kinda frustrated with all these different lens designs not having pertinent info printed on the box, what's up with that?

    You should be able to get the "tech" sheet on all of these. I'll try and look it up for you Monday - if you can wait. I think I have it on my backup drive.

    Thanks I really really really would aprreciate it. It's not available on the box like most usually are, and the sites cater more towards the dispenser than the lab so that kinda stuff is usually hidden deep in the bowels if it's even there at all.

    Harry:

    I thought you use Innovations. Why don't you just use the updated lens specs?

    That would be the boss' choice, but its not smart.

    Of course, I know software people that don't believe in getting new glasses.
