Zero Order Waveplates(Optically Contacted,Cemented by Epoxy,Air spaced)
Introduction for Zero Order Waveplates
Zero order waveplate shows better performances than multiple order waveplates, it has broad bandwidth and a lower sensitivity to temperature and wavlenght changes
1. Zero Order Waveplate - Optically Contacted
This type of zero order waveplate is constructed of two multiple order waveplate with their axes crossed.Thus,the effect of the first plate is canceled by the second,except for the residual difference between them.
• Optically Contacted
Standard Wavelength:
266nm 355nm 400nm 532nm 632.8nm 780nm 800nm 808nm 980nm 1064nm 1310nm 1480nm 1550nm 1800nm
Note for waveplate:
2. Zero Order Waveplate - Cemented by Epoxy
This type of zero order waveplate is constructed of two multiple order waveplate with their axes crossed.Thus,the effect of the first plate is canceled by the second,except for the residual difference between them.
