High-Power Zero Order Waveplate

High-Power zero order waveplateHigh-Power(Optically Contacted) Zero Order Waveplates are constructed of two multi-order Quartz waveplates, by optically contacting method. The fast axis of one plate is aligned with the slow axis of the other, with an optical path length difference of λ/4 or λ/2. Compound zero-order waveplates provide wide tunability about the design wavelength. They also offer excellent temperature stability as temperature effects of the two components parts tend to cancel out.


- Higher Damage Threshold

- Center Wavelengths from 266 nm to 2020 nm

- Relatively insensitive to wavelength and temperature variation

- Retardations of λ/2 and λ/4

- OEM Pricing Available Upon Request
