True Zero Order Waveplates
Superior broadband performance.
Extremely miniature thickness for precise retardation.
Excellent retardation consistency with changes in wavelength, ambient temperature, and incident angle.
Applications: Optical communication systems, Quantum computing and cryptography, Laser systems and high-energy applications, Polarization-sensitive imaging and detection, Biomedical imaging and diagnostics, etc.
True zero order waveplate is an advanced and improved version of zero order waveplates, offering superior broadband performance. Unlike net zero-order waveplates that generate the desired retardance by stacking two multiple-order waveplates, true zero-order waveplates feature extremely miniature thickness to provide exactly the required retardation. This unique characteristic ensures excellent retardation consistency, even with changes in wavelength, ambient temperature, and incident angle.

Type 1: Quartz Free-standing Single Plate
- High damage threshold (>1GW/cm2@1064nm, 10ns, 10Hz), suitable for high-energy applications.
- Standard wavelengths range from 532nm-1550nm, with customization available.
- Minimum thickness produces π/2 phase delay for 800nm light source and π/4 phase delay for 1550nm light source.
Type 2: Quartz Single Plate + BK7 Substrate
- Strengthened with BK7 substrate using NOA61 cement or optical bonding for easier operation.
- Capability limit down to 355nm (excluding 355nm).
- Reduced damage threshold (1~2J/cm2@1064nm, 10ns, 10Hz) for cemented modules, but can be raised to 15J/cm2 using diffusion bonding.
Type 3: MgF2 True Zero Order Waveplates
- Made of Magnesium Fluoride, recommended for long-wavelength operations (e.g., wavelengths above 3000nm).
