Crystalline quartz waveplates

Description

Zero Order (ZO), Low order (LO) or Multiple order (MO) half or quarter waveplates, polarization rotators for UV, VIS and NIR (for any wavelength in 240-2600 nm range)

To suit different applications, air spaced, glued or optically contacted Zero Order compensated phase retardation plates are available.

Waveplates are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. This difference in velocities gives rise to a phase difference when the two beams recombine. At any specific wavelength the phase difference is governed by the thickness of the retarder - waveplate.

Half (λ/2) Waveplate. A linearly polarized beam incident on a half wave crystal quartz waveplate emerges as a linearly polarized beam but rotated such that its angle to the optical axis is twice that of the incident beam. Therefore, half-waveplates can be used as continuously adjustable polarization rotators. Half-waveplates are used to rotate the plane of polarization, electro-optic modulation and as a variable ratio beamsplitter when used in conjunction with a polarization cube.

Quarter (λ/4) Waveplate - thin-film compensator. If the angle between the electric field vector of the incident linearly polarized beam and the retarder principal plane of the quarter-waveplate is 45, the emergent beam is circularly polarized. When a quarter waveplate is double passed, i.e. by mirror reflection, it acts as a half waveplates and rotates the plane of polarization to a certain angle. Quarter waveplate are used in creating circular polarization from linear or linear polarization from circular, ellipsometry, optical pumping, suppressing unwanted reflection and optical isolation.
Zero Order waveplates are generally preferred since they are least sensitive to variations in wavelength, angle of incidence and temperature.

Air-spaced crystal quartz waveplates are also available. Its performance is as good as cemented zero-order waveplate. Additionally, the air-spaced construction enables it is suitable for the high power laser application. The damage threshold is more than 500 MW/cm2.

Phase retardation plates - waveplates for the IR range, polarization rotators, Faraday isolators are available on request!
