What happens when a wave is refracted?

Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves. So if the medium (and its properties) is changed, the speed of the waves is changed.

What causes refraction of a wave?

Refraction is caused by the wave’s change of speed. Refraction occurs with any kind of wave. For example, water waves moving across deep water travel faster than those moving across shallow water. A light ray that passes through a glass prism is refracted or bent.

What is refraction in relation to waves?

Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than in shallow. The speed of sound waves is greater in warm air than in cold.

How does the birefringence of a beam displacer work?

In our beam displacers, this birefringence laterally separates the two orthogonal polarization states of an incident beam.

When to use a calcite beam displacing polarizer?

When unpolarized light is normally incident on the optic, ordinary rays travel straight through the crystal while extraordinary rays exit the crystal displaced by a distance that depends on the light’s wavelength and the length of the crystal. A calcite beam displacing polarizer is used to separate the orthogonally-polarized components of a beam.

How are calcite beam displacers mounted in Thorlabs?

Fabricated from a single piece of the highest quality optical grade calcite, our beam displacers can be used with wavelengths from 350 nm up to 2.3 μm. Since calcite is a soft crystal that can be easily damaged, our calcite polarizers are housed in a Ø1″ metal housing that can be mounted into our optomechanical rotation mounts.
