Product description
We can provide two types of true zero-order waveplates, namely single-piece true zero-order waveplates and cemented true zero-order waveplates, and waveplates can be customized according to customer needs.
Single-piece True Zero-order Waveplate: It is processed from a single piece of quartz crystal and has a very high delay accuracy. Compared with ordinary zero-order waveplates, its performance is more stable, and it is minimally affected by factors such as temperature and materials. It is often used in some high-precision applications, such as optical communication, scientific research, and other fields.
Cemented True Zero-order Waveplate: It is formed by cementing a single piece of quartz crystal and a fused quartz substrate. Compared with the single-piece true zero-order waveplate, its physical strength is greatly improved, and its performance is almost the same as that of the single-piece true zero-order waveplate.
Characteristics:
- True zero-order phase delay
- Customizable wavelength: 150-7000nm
- All surfaces are coated with anti-reflection film
- High damage threshold (single-piece)
- Extremely high phase delay accuracy
