Ultraviolet Polarization
Bolder Vision offers a dichroic polarizer laminated between two pieces of recommended UV grade fused silica. Custom patterns may be cut for maximum flexibility. The ultraviolet spectrum posses unique challenges to manufacturing which, our optical engineers will be glad to discuss with you.
