Important: Do not use Polarizing Filters to view the August eclipse. They are not safe for this purpose.

When two polarizing filters are placed atop one another, they can be transparent or opaque to light. By rotating one of the filters, the transmitted light passing through the filters may be turned 'on' or 'off'. Certain materials such as polyethylene, cellophane tape, plexiglass, and corn syrup can exhibit beautiful colors when placed between two polarizing filters.

These high quality plastic polarizing filters are perfect for all kinds of experimentation. Can be cut with scissors or an ordinary paper cutter. Sold individually. Available in various sizes. (Sizes are approximate.)

Please note: Our polarizing filters originate on a large roll and may be slightly curved when you receive them. If you need a filter to lie flat, you can bend it in the opposite direction to flatten it and/or place it between two heavy flat surfaces, such as text books.
