Product description
We can provide various types of zero-order waveplates, including optically contacted zero-order waveplates, air-spaced zero-order waveplates, and cemented zero-order waveplates. Waveplates of various wavelengths can be customized according to customer requirements.
The zero-order waveplate is composed of two multistage quartz waveplates. Through phase cancellation, the effect of a zero-order waveplate is achieved. Compared with multistage waveplates, zero-order waveplates are less sensitive to temperature and wavelength, and can work under a relatively large acceptance angle. They can be used in optical systems with high precision requirements.
Material Selection: Quartz crystal or MgF₂ crystal material.
Characteristics:
- Air-gap or optical contact design
- Customizable wavelength: 150-7000nm
- All surfaces are coated with anti-reflection film
- High delay accuracy
- Insensitive to ambient temperature
