hi there

I think you are going to have to elaborate a bit more

particularly where you got an idea of minimum and maximum wavelengths
references ??

what sort of polarisers ? sun glasses type ?, camera type?, scientific use ones ?

The polariser I use on my camera works well across the full visible spectrum
maybe further each way, I have no idea
