Principles of Waveplate

Half Waveplate

The thickness of a half waveplate is such that the phase difference is 1/2-wavelength (true-zero order) or some multiple of 1/2-wavelength (multiple order).

Quarter Waveplate

The thickness of the quarter waveplate is such that the phase difference is 1/4 wavelength (true-zero order) or some multiple of 1/4 wavelength (multiple order).

Single Plate True Zero order Waveplate

• Broad Spectral Bandwidth
• Wide Temperature .Bandwidth
• Wide Angle Bandwidth
• High Damage Threshold

Low Order Waveplate

• Thickness: 0.2-0.5 mm

• High Damage Threshold

• Low Cost

Optically Contacted True Zero Waveplate

• Optically Contacted

• Thickness 1.5~2mm

• Double Retardation Plates

• Broad Spectral Bandwidth

• Wide Temp. bandwidth

Air Spaced Zero-Order Waveplate

• Double Retardation Plates

• AR Coated,R<0.2% and Mounted

• High Damage Threshold

• Better Temperature Bandwidth

• Wide Wavelength Bandwidth
