Just trying to figure out the kind of coating used on the older anamorphic lens elements such as the Todd-Ao/Older Panavision/old lomos which gives them a strong blue flare. Someone once told me what the coating was but I cant seem to recall it. Thanks for any help!

About russian LOMO lenses.
All professional cinema lenses, spherical , anamoprhic have coating.
The russian old anamoprhic lenses, with square front glass, NAS, BAS have cooating too.
The procedure of re-coating ask special technical request from lenses.
The componnets must be do not glue, because, high temperature coating can destroy of glue.
The procedure re-loading ask of additional tools for polisnig of old surface and keep value of
surface curvature of glass component.
Thta's why, the procedure re-coating expencive and do not profitable for single lens.

Thanks for your knowledge olex- Im not trying to recoat a single lens, but do a whole batch of non- anamorphic stand alone glass optics- Are you able to do this sorta thing Olex? Looking for that same coating on the old squarefront lomos circa the first Solaris.

The last quote I got from a couple years back on lens re-coating was $195.00 per surface. Take an easy lens with only seven elements and it comes out to $2,730.00 to re-coat the whole thing. As you might guess, re-coating isn't done very often. I think it is worth it if you have a very good lens with something like only outer element wear. Your stand-alone scope-ments might be worth it. I can see some sense in that.

It also makes me wonder if they could be put in front of my Nikons with any success.

Thanks Paul- Yes, I would be crazy to recoat a whole lens assembally. Im just trying to get a lot of single lens elements coated with that particular coating (or similar). Maybe this is a job for Dan Sasaki?

Think I figured it out- some sort of single layer of a magnesium floride mix.
