High Quality Quartz Zero Order λ/2 λ/4 Waveplate (Retarder)

Description

UM Optics High Precision Quartz Waveplates are premium polarization control components engineered for demanding industrial, scientific, and laser-based applications. Crafted from high-purity quartz crystal, these waveplates offer exceptional temperature stability and low wavelength sensitivity, ensuring reliable performance even in harsh operating environments.As a professional manufacturer, we provide a comprehensive range of quartz waveplates, including λ/4 (Quarter-Wave), λ/2 (Half-Wave), zero-order, and multi-order options. Each waveplate is precisely fabricated to deliver accurate phase retardation, with high extinction ratio (>1000:1 typical) for optimal polarization state conversion. The surface is coated with anti-reflective (AR) coating (customizable for UV, VIS, or IR wavelengths) to minimize light loss and enhance transmission efficiency.

Frequently Asked Questions

What is the difference between Quarter Waveplates and Half Waveplates?

Quarter Waveplates transform linearly polarized light into circularly polarized light, and vice-versa. Half Waveplates rotate the plane of polarization of linearly polarized light through any angle. They also convert left circularly polarized light into right circularly polarized light, and vice-versa.

Can quartz waveplates be customized for specific wavelengths or sizes?

Yes, we offer full customization. Our quartz waveplates can be tailored for wavelengths ranging from 200nm (UV) to 2000nm (IR). Size customization is also available, with options from φ1mm (microscopic) to φ100mm (large-format). Additionally, we can add custom anti-reflective (AR) coatings to enhance transmission efficiency for your target wavelength.

Why are anti-reflective (AR) coatings applied to quartz waveplates?

Anti-reflective coatings are applied to minimize light reflection at the waveplate surfaces, reduce light loss, and enhance transmission efficiency, ensuring more stable and accurate polarization control performance.

How to choose the right type of quartz waveplate (zero-order vs multi-order) for my project?

Zero-order quartz waveplates are recommended for high-precision scenarios (e.g., quantum communication, laser ranging) as they have low wavelength sensitivity and excellent temperature stability. Multi-order waveplates are more cost-effective and easier to manufacture, suitable for industrial inspection or teaching experiments where temperature and wavelength variations have minimal impact on performance.
