Abstract

The narrow-pass-band polarization filters are mentioned. Several methods are used for such type of filters. The construction of narrow-band interference polarization filters with liquid crystal space (LC) layer has been presented. The peak of transmittance has been designed at wavelength 1064 nm. Refractive index of liquid crystal changes with driving voltage. At optical thickness of space layer changed to the multiple of quarter-wave thickness the construction has a stop-band in interested spectral range.
