Description

Quartz waveplates are precision optical retardation components fabricated from high-quality quartz crystal. Utilizing the birefringence property of quartz crystal, they generate a specific phase difference between two orthogonal polarized light beams. Featuring strict crystal axis orientation, high surface finish and precise retardation accuracy, quartz waveplates deliver stable polarization modulation performance over a wide wavelength range. They are widely used to adjust, convert and control the polarization state of laser beams, ideal for laser systems, polarization spectroscopy and high-precision optical experimental setups.

Frequently Asked Questions

What is the working principle of a quartz waveplate?
It adopts the natural birefringence of quartz crystal. When polarized light passes through, two mutually perpendicular light waves propagate at different speeds, forming a fixed phase difference to realize polarization conversion.
What is the difference between 1/4 waveplate and 1/2 waveplate?
A 1/4 waveplate converts linearly polarized light into circularly polarized light; a 1/2 waveplate rotates the polarization angle of linearly polarized light without changing its polarization type.
What is the main difference between zero-order and multi-order quartz waveplates?
Zero-order waveplates provide exactly one wavelength of phase retardation with very low temperature and wavelength sensitivity. Multi-order waveplates are composed of multiple integer wave orders, thicker in size, more sensitive to ambient temperature and wavelength shift, but with lower cost and easier processing.
