Both linear and circular polarisers are available from Lee Filters in both a rotating 105mm diameter ‘screw in’ version and a 100x100mm square version. The 100mm square polarisers are to be used in the filter holder in a standard 2mm resin filter slot; and the entire holder is then rotated to achieve the correct polarisation state.This is recommended for studio use or for when only the polariser and, possibly, standard filters are to be used.
