25.4mm Dia., λ/2 at 800nm and λ/4 at 400nm, Dual Wavelength Waveplate

Product Details λ/4 and λ/2 Retardance for Harmonic Separation Designed for Nd:YAG, Yb:YAG, or Ti:Sapphire Lasers Multiple Order Designs Dual-Wavelength Quartz Waveplates are made with high-quality crystalline quartz substrates and offer λ/4 retardance at one wavelength and λ/2 retardance at a second wavelength. Featuring designed wavelengths for Nd:YAG (532 and 1064nm), Yb:YAG (515 and 1030nm), and Ti:Sapphire (400 and 800nm), these waveplates boast high laser damage threshold (LDT) and anti-reflective (AR) coatings for high powered laser applications. Dual-Wavelength Quartz Waveplates are mounted in a 25.4mm black anodized aluminum ring with an 18mm clear aperture. These waveplates are ideal for laser separation applications requiring increased conversion efficiency of dual-wavelength sources or Second-Harmonic Generation (SHG) lasers through management of polarization.
