Description

Magnesium Fluoride (MgF₂) waveplates are high-performance polarization optical components made from premium single-crystal magnesium fluoride. Leveraging the natural birefringence of MgF₂ crystal, they produce precise phase retardation for polarized light. Featuring ultra-broad spectral transmission from deep UV to infrared, low intrinsic fluorescence and excellent radiation resistance, MgF₂ waveplates maintain stable polarization performance under deep ultraviolet and high-energy laser irradiation. They are ideal for polarization modulation, beam control and spectral measurement in UV laser systems and high-sensitivity optical instruments.

Frequently Asked Questions

What are the advantages of MgF₂ waveplates compared with quartz waveplates?

MgF₂ waveplates have better deep UV transmittance, lower fluorescence and stronger anti-radiation performance, making them more suitable for deep ultraviolet and high-energy laser applications where quartz cannot work stably.

Does MgF₂ waveplate support zero-order design?

Yes, it can be fabricated into zero-order retardation structure to achieve ultra-low wavelength and temperature sensitivity for high-precision broadband UV optical systems.

What is the main difference between zero-order and multi-order 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.
