Air Spaced Zero Order High Power Waveplate 1030/1310/1550nm 25.4mm Diameter Quarter Half Wave Crystal Quartz for Fiber Laser Scientific Research Industrial Optics (360° Rotation mount-25.4)

Air Spaced Zero Order High Power Waveplate 1030/1310/1550nm 25.4mm Diameter Quarter Half Wave Crystal Quartz for Fiber Laser Scientific Research Industrial Optics (360° Rotation mount-25.4)

• Telecom & Yb‑Laser Wavelengths – Three critical near‑IR lines: 1030nm (Yb:YAG/fiber), 1310nm (O‑band telecom), 1550nm (C‑band telecom & LIDAR). Each waveplate is individually coated and tuned for its specific wavelength – no broadband compromises.
• Air‑Spaced Zero‑Order Design – Two quartz plates with an air gap eliminate the temperature (±0.05%/°C typical of multi‑order) and wavelength drift issues. Retardation stays accurate from 15°C to 35°C – ideal for uncooled laser diodes and outdoor fiber systems.
• Ultra‑High Damage Threshold – >20J/cm² (20ns, 20Hz @1064nm); even higher at 1310/1550nm due to lower photon energy. No organic cement means no absorption, no outgassing. Suitable for high‑power CW, nanosecond pulsed, and ultrafast (fs/ps) lasers.
• Precision Specifications – Retardation tolerance <λ/300, surface quality 20/10, wavefront distortion <λ/8 @632.8nm. AR coating R<0.25% at center wavelength minimizes insertion loss – critical for fiber optic power budgets.
• Fully Mounted & Ready to Use – Housed in a Ø25.4mm black anodized ring with 20mm clear aperture. Drops directly into standard 1‑inch rotation mounts. Protective storage case included. Backed by PhotonEdge quality.
