Mounted foil filters

The company Seymour Solar from Utah, USA specialises in the manufacture of solar filters. The filters are housed in a stable aluminium casing, and are attached to an optic and fixed into place with lateral clamping screws. Since many brands have their solar filters manufacturered by Seymour Solar, these filters are very often found under other brand names.

Seymour Solar manufactures filters made of film and of special mirror plane-parallel glass.
