blue,purple and a bit of UV+IR

Yes, that would be an informative comparison.

I just looked at it. interesting topiс!!!

 

СС4+СЗС26

Something about green:

 

Here are some tests of the gradient for visible green for ПС11 and other filters. All in a stack with 2 mm S8612.

 

I did this tests for myself before. The gradient cut after visible red, so this testing is only for the UV-visible part.

(U 360 - just for comparison - where the UV gradient ends.)

 

So yes, as Cadmium said - ПС11 show green.

For 3 mm, but for 5 mm very little, if raise the brightness. For street photo, it doesn’t matter probably.

 

BG3 for 2 mm and thicker, does not transmit green..

 

I also want to say - I like ФС1 3 mm in comparison - the only thing close to ПС11, and does not show green. Аnd generally looks good, if no BG3.

Same for BG3. All the data are the same.

The best filters are Schott, they make the best glass in most cases, and they have the absolute best data and graphs of any filter maker in the world.

 

Yes, Schott filters are the best, modern, thin, all better. However, people sometimes only start with inexpensive Chinese or Russian filters. So just comparison of filters interesting for, probably..

But of course, everyone will receive the Schott filters as soon, as it possible.

 

The most complete catalog about Russian filters is here:

Evgeniya, Very nice comparisons. ПС11 and BG3 are similar, but ПС11 should have more red in it than BG3, like on this graph:
