Broadband Polarizer BBPOL
Separates the s- and p-polarized light in a broader range compared to the standard TFP but normally with a lower extinction ratio. It can be made by using a plate coated on both sides and a large angle of incidence (AOI~72°) or a cube (special glass material is required) .

The extinction ratio can be optimized for use in reflection or transmission. The given values refer to the standard TFP made by IBS and the much cheaper EBE. Also other splitting ratios, e.g. Tp/Rs can be optimized.

All values are given for standard coatings. Customized coatings available for all types.
