Zero Order Waveplates-Optically Contacted

Optically contacted zero order waveplate is constructed by two quartz plates with their fast axis crossed, the two plates are constructed by optically contacted method, the optical path is epoxy free. The difference in thickness between the two plates determines the retardation. Zero order waveplates has a lower sensitivity to temperature and wavelength changes.

• Optically Contacted 
• Double Retardation Plates
• AR Coated, R<0.2%
• High Damage Threshold 
• Better Temperature Bandwidth
• Wide Wavelength Bandwidth

Zero Order Waveplates - Cemented by Epoxy

Cemented zero order waveplate is constructed by two quartz plates with their fast axis crossed, the two plates are cemented by UV epoxy. The difference in thickness between the two plates determines the retardation. Zero order waveplates has a lower sensitivity to temperature and wavelength changes.

• Cemented by Epoxy  
• Double Retardation Plates
• AR Coated, R<0.2%
• Better Temperature Bandwidth
• Wide Wavelength Bandwidth

Zero Order Waveplate - Air spaced

Air spaced zero order waveplate is constructed by two quartz plates installed in a mount, to form a air gap between the two quartz plates. The difference in thickness between the two plates determines the retardation. Zero order waveplates has a lower sensitivity to temperature and wavelength changes.

• Air Spaced  
• Double Retardation Plates
• AR Coated, R<0.2%
• High Damage Threshold 
• Better Temperature Bandwidth
• Wide Wavelength Bandwidth
