Title: Light Polarizing Filter Source
Post by: ken099990 on June 05, 2024, 09:23:59 pm

Anyone know of a good source for purchasing Light Polarizing Filters in the USA?

Any help is greatly appreciated.

I don't know how big you want but I use a 200mm square of this for my studio strobes:

You don't say what size/shape or application?  With that said, I use polarizers from Breakthrough Photography (https://breakthrough.photography).  Their filters have a very flat transmission curve and are without color cast.  Free shipping in the USA.

We typically buy all of our gels from a local theatrical supply store, most of which are official Rosco dealers.  Rosco makes a polarizer gel that my wife uses to cross polarize her lights in studio when needed.  It usually is a special order item though, and they are not cheap.  Also, it is important to keep the modeling lights turned off since warping due to heat will cause the polarizer to become less polarized the more it warps.
