Zero order waveplates
from 266 nm to IR | >10 J/cm2 at 1064 nm
A zero-order waveplate consists of two low-order plates with their optical axes crossed. This configuration cancels the plates’ retardation, while the required retardance is achieved by adjusting the thickness of the two plates. These waveplates are designed to provide the desired retardance without introducing additional wavelength shifts that occur in low order waveplate.
Where Are Zero-Order Waveplates Used?
3photon recommends zero-order waveplates in applications requiring increased sensitivity where low order waveplate are insufficient.They perform well across broader bandwidths and are less sensitive to temperature or wavelength variations compared to low order waveplates. Zero-order waveplates can also be used in the same fields as low-order waveplates but offer reduced sensitivity to temperature and wavelength changes, making them ideal for diode, femtosecond, and tunable lasers.
3photon offers three designs of zero-order waveplates:
- Cemented Zero-Order Waveplate: Transparent optical glue bonds the two plates together.
- Optically Contacted Zero-Order Waveplate: Van der Waals forces bring the two plates into contact.
- Air-spaced zero order waveplate: a special design that has a vacuum layer between two plates to cancel out the disadvantages that occurs with optical glue and optical contacted layers.
Depending on the design, the damage threshold, wavefront distortion, and laser beam deviation vary. The air-spaced design, though the most expensive, offers the best specifications for zero-order waveplates.
