The half waveplate is used to change direction of the linear polarization.When the crystal axis (fast axis or slow axis) is aligned parallelyl with the polarization direction of the incident beam, the polarization of the exit beam will maintain the same direction.When the crystal axis of the waveplate is rotated for θ from polarization direction of the incident beam, the polarization of the exit beam rotates for 2θ from polarization direction of the incident beam.Using this effect, the direction of the linear polarization is arbitrarily rotated with the rotation of the half waveplate.This method has a merit that the polarization direction is rotatable without change in light intensity.When the polarization direction of the waveplate is rotated for 90°, the extinction ratio of linear polarization is slightly deteriorated due to the retardation error. For this reason, insertion of a polarizer next to the waveplate is recommended for the precise polarization measurement, which requires high extinction ratio.
By combining the polarization beam splitter (PBS) and half waveplate, it is possible to vary the light intensity.
One of the features is dynamic range of light intensity adjustment. (97% to 0.3%, depending on the quality of the PBS)
A half waveplate is used when aligning P and S-polarized light which is separated by PBS into same polarization direction.Below is an example of optical system to expose the grating by two-beam interferometry.Interference fringes with good contrast can be obtained by aligning the polarization direction.

the laser.An optical isolator is used to prevent this returning light.A typical optical isolators are composed of quarter waveplate and a polarizer.
degrees is obtained from phase difference amount of twice passed through the quarter waveplate.
Feature of quarter waveplate is that it is possible to convert incident linear polarization into circular polarization, but also into other state of linear polarization or various elliptical polarization.Conversely, when elliptical axis of incident light is accurately aligned against quarter waveplate optical axis, arbitrary elliptical polarization can be converted into linear polarization.The azimuth γ
The polarization measurement using this principle is named Senarmont method.Senarmont method is commonly used when measuring minute stress (birefringence).
A Michelson interferometer using a PBS and quarter waveplate is introduced.
Incident light is collected on the observation side without a loss, but in order to observe polarization, insertion of the polarizer is demanded with 50% reduction of light intensity.

Hof crystalline quartz plates and are mounted on aluminum frames.
Air spaced type two-piece waveplates. Compatible with high-energy lasers (no optical contact occurs). These products utilize birefringence of quartz and give phase difference of λor λ λ/4 retarders convert linearly polarization to circularly and circularly polarization to linearly. λ/2 retarders convert the direction of polarization arbitrarily.
▶Custom-made air spaced type broadband quartz waveplates for
other wavelengths are also available. Please feel free to contact us.
▶Standard thickness of Aluminum frame is 6mm (subject to differ
without notice).
▶Optical axis is parallel to the edge of 14mm squared plate.
▶These products can be used for the beams which wavelengths are in
▶before coating.
▶Be sure to wear laser safety goggles when checking optical path and
adjusting optical axis.
