 Polarizing Beamsplitters

The main difference between a polarizer and a polarizing beamsplitter:

  • In the polarizer only one polarized beam is required;
  • In the polarizing beamsplitter both beams are to be utilized.

A polarizing beamsplitter can be used as a polarizer. The performance in transmission or reflection of both devices is usually characterized by their degree pf polarization or by the extinction ratio ER:

\[ ER=\frac{T_{desired}}{T_{undesired}} \]

In a polarizing beamsplitter a high degree of polarization is required in both beams and it is more difficult to achieve.

In order to specify the desired specifications, special (user-defined targets) can be used.

Example: 21-layer polarizing beamsplitter for the spectral range from 520 nm to 560 nm and incidence angle of 45 degrees.

Incidence Medium is Glass and Substrate is Glass. The coating is cemented between two Glass substrates.

Extinction ratio is more than 3000.
