Polarizers

 

Polarizers are optical filters that pass radiation of a specified polarization and blocks radiation of other polarization.

Thin-film linear polarizers are glass substrates with specially designed and deposited optical coatings (polarizers). The thin film polarizer can either be parallel, working at a particular incidence angle, or a wedge of glass that is cemented to a second wedge to form a polarization cube with the optical coating cutting diagonally across the center.

Example: A 50-layer thin film polarizer designed by OptiLayer for the spectral range from 780 nm to 820 nm and the incidence angle of 45 degrees. Materials: Nb2O5 and SiO2; Thinnest layer is 64 nm.

Ratio Ts/Tp=400.

You can design such a filter in several seconds.

You can reduce the number of layers step by step (for example, removing neighbor pairs of layer H and L) and make the refinement and obtain a  structure  with a smaller number of layers. With the of Digitize option you can control the ratio between Ts and Tp and achieve a balance between the required ratio as well as acceptable number of layers.thin film polarizer
