Can someone tell me how to check the stroke on the SatisLoh cylinder machines?

So if I apply prentices rule to get the prism for Decentration it is in the index of the lens?

Hello All

Can anyone give me an explanation of how index of refraction affects prism in a lens? I have set up software and procedures for prism expressed in the tooling index and in one where...

have you heard of an alternative

Hi

I work in a lab in OK and we do our own slab offs and everything goes really well till we get to poly. We use Paul Mitchell or Aqua Net hair spray to protect the top of the lens when we add...

Can anyone give me a number to the Komodo AR company

Over time I have always wondered how a Aspheric Lenticular is figured by hand. I have used a couple of different programs with differing levels of success. Does anyone out there know how to...

I am looking for a good used Sag gauge to check tools. I prefer a 50 mm bar on a stand

I have one of those "crystal cut" facets. It is a 56 eye now and they need a 53 eye in the new glasses

Thanks for all of the help everyone

I appreciate the help. Can anyone give me an ballpark idea of the increase. for a +5 rx might we expect as much as a .5 mm increase from a 6 base to a 10 base.

I want to thank everybody for their help with my last question and see if I can get some more help. If I grind the same plus rx with 3 different base curves (for example +6 -4 in aq 6 8 and 10...

Thank you Davaid I appreciate the help. I will give this a try
