What is the difference excactly? if anyone knows?
I have been searching and searching for a Polarizing beamsplitting cube for 405nm and over 25mm in size for a long time now but cant find any.
Today i talked to "Thorlabs" and they have some "nons" and said i could probably use "non Polarizing". but they sound litle unsure.
any suggestions?
thnx
