Cemented Zero Order Waveplates are built by cementing two multi-order Quartz waveplates 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.
Features:
- 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
