Polarizing filters have the property of transmitting light that vibrates in one direction while absorbing light that vibrates in a perpendicular direction. These filters are used extensively in scientific instruments. In sunglasses and when placed over a camera lens, polarizing filters reduce unwanted reflections from…

…liquid crystals, are placed between polarizing filters crossed in this manner, some light may get through, because the intervening material changes the polarization of the light. If the nematic director is not aligned with either of the polarizing filters, polarized light passing through the first filter becomes partially polarized along…
