R<0.25% AR Coating, >500mJ/cm² Damage Threshold | Cemented Zero Order 532nm Half/Quarter Waveplate for Green Laser Polarization Control (WPZ532Q-07)

Need stable, precise polarization management for your 532nm green laser system? Our cemented zero-order waveplate is optimized for 532nm single wavelength. Two quartz plates with crossed fast axes are UV-cemented, eliminating the temperature drift and wavelength sensitivity of multi-order plates for true zero-order retardation. 532nm-specific coating: Dual-side AR, <0.25% reflection at central wavelength, ultra-low insertion loss. High-precision retardation: Tolerance 500mJ/cm² (1064nm, 20ns) – same process applicable to 532nm, suitable for nanosecond green lasers. Beam quality preserved: 20/10 scratch-dig, 90%. Flexible options: Half waveplate (rotate linear polarization) or quarter waveplate (linear↔circular). Specify type when ordering.

• Optimized for 532nm wavelength – AR coating R<0.25% at center wavelength; both half and quarter waveplates designed for green lasers.
• True zero-order cemented design – Superior temperature and wavelength bandwidth vs. multi-order plates; minimal retardation drift with environment.
• Ultra-high retardation accuracy – Tolerance <λ/300, meeting demanding polarization requirements in R&D and industrial laser systems.
• Robust for laser processing – Damage threshold >500mJ/cm² (tested at 1064nm, comparable at 532nm); UV-cemented for durability.
• Precision optical specifications – 20/10 scratch-dig, wavefront distortion <λ/8@632.8nm, parallelism <1 arc second, clear aperture >90%.
