Quartz waveplate #4354

dual-wavelengthfor linear polarization conversion

Overview Dual-wavelength quartz waveplates provide quarter-wave (λ/4) retardance at a primary wavelength and half-wave (λ/2) retardance at a secondary wavelength using crystalline quartz substrates and precision thickness control. They include anti-reflective (AR) coatings and are available in multiple-order designs with high laser damage threshold (LDT), suitable for integration in high-power laser systems.

Features

• λ/4 and λ/2 retardance for harmonic separation and polarization management
• Designed for Nd:YAG (532/1064), Yb:YAG (515/1030) and Ti:Sapphire (400/800)
• Multiple-order and thin-plate design options
• Anti-reflective (AR) coatings optimized for the wavelength pairs
• High laser damage threshold (LDT) for high-power operation
• Mounted in 25.4 mm black anodized aluminum ring with 18 mm clear aperture
