Hi Guest: Ordinary visible light linear polarizers work the best. Circular polarizers can also be used but the birefringent material used in them must not be between the two polarizers (reverse them) otherwise they will not go to extinction when crossed. The large polarizing sheet material is available at Surplus Shed and is economical. Experiment with different materials and subjects. Isotropic materials like glass are not birefringent, while most plastics are. Ice crystals such as snow are birefringent and are very beautiful in polarized light. See my "Through the Microscope" gallery for some examples using crossed polarizers on a microscope.

Pretty impressive images, especially those were the rainbow effect appears. I'm little curious what kind of polarizer i'll need to do the same. I found these www.codixx.de/cms/polarizers/polarizer/polarizing-filters/ir-infrared-vis-visible.html which seems to address the related spectra range, but i'm not sure if they will fulfill the needs? Any hints?
