Product Introduction
A waveplate, also known as a phase retardation plate, is an optical device that can produce an additional optical path difference (or phase difference) between two mutually perpendicular light vibrations. It is typically made of birefringent crystals such as quartz, calcite, or mica with precise thicknesses, and its optical axis is parallel to the surface of the plate. When linearly polarized light is incident perpendicularly on the wave plate, its vibration direction forms a certain angle with the optical axis of the plate, thereby decomposing into two components: one perpendicular to the optical axis (o-vibration) and the other parallel to the optical axis (e-vibration). These two components propagate at different speeds (with different refractive indices) within the crystal, resulting in an optical path difference and subsequently a phase difference upon exiting the crystal. Wave plates can be used in the following applications:
Polarization Control: Wave plates can be combined with other optical elements (such as polarizers, lenses, and mirrors) to form more complex optical systems for controlling the polarization state of light.
Interferometry: In interferometry, wave plates are used to adjust the polarization state of light to achieve more precise measurements.
Lasers: Wave plates have various applications in lasers, such as wavelength combining and separating, Q-switching, and destructive interference quenching.
