Description

The OPTOMAN QWP-AS-ZO-515-25.4 is a precision zero-order air-spaced quarter-wave plate engineered for demanding polarization control applications at 515 nm. Manufactured from premium crystalline quartz, it introduces a precise λ/4 phase retardation for efficient conversion between linear and circular polarization while maintaining outstanding optical performance. Its air-spaced construction minimizes sensitivity to temperature fluctuations and wavelength variations, making it an excellent choice for high-power and ultrafast laser systems.

Designed for second-harmonic (515 nm) Yb-based femtosecond lasers, this waveplate delivers excellent transmitted wavefront quality, low beam deviation, high retardation accuracy, and low residual reflectance through its anti-reflection coating. The robust black anodized metal mount ensures reliable alignment and long-term stability in research laboratories, industrial laser processing systems, spectroscopy setups, and advanced photonics applications.

Frequently Asked Questions

What is the QWP-AS-ZO-515-25.4 used for?

The waveplate is designed to convert linearly polarized light into circularly polarized light, or circularly polarized light back into linear polarization, providing precise polarization control in 515 nm laser systems.

Why is a zero-order air-spaced design beneficial?

A zero-order air-spaced waveplate offers significantly better stability against temperature and wavelength changes than multiple-order designs, resulting in more accurate retardation and consistent long-term performance.

Which laser systems is this waveplate compatible with?

It is optimized for 515 nm second-harmonic outputs from Yb-based ultrafast lasers and is suitable for many femtosecond laser platforms used in scientific, industrial, and research applications.

Can this waveplate be used with high-power lasers?

Yes. The crystalline quartz substrate, air-spaced construction, and low-reflectance AR coating make it well suited for demanding high-power and ultrafast laser environments when operated within the manufacturer's specified limits.

What optical characteristics contribute to its precision?

The waveplate combines a ±λ/300 retardance tolerance, transmitted wavefront distortion below λ/10, beam deviation under 10 arcseconds, high-quality 20-10 scratch-dig surfaces, and low residual reflectance, helping maintain excellent beam quality in precision optical systems.
