TeO2 Beam Displacer & Beam Polarizer

 

BD separates the incident beam into two linearly polarized beams with orthogonal polarizing orientation.

BP gives linear polarizing light.

Application - microscopes, interferometers etc.

 

- One piece crystal with a special orientation of the    optical axis

- Outer beams are parallel to each other at a specified distance

- Ordinary ray propagates without changes, extraordinary - deflects inside the crystal

- In BP - extraordinary ray is absorbed by the side surface

- Minimum absorption over the whole range of use from 0.35 to 5 um

Type BP6  - separation distance of the output beam is 6 mm for 633 nm

Type BP7  - separation distance of the output beam is 7 mm for 633 nm

 

Type BD3 - separation distance of the output beam is 3 mm for 633 nm
