Important Specifications
Wavelength Range
Half-wave plates are designed for specific wavelengths or wavelength ranges. Common discrete wavelengths include 266 nm to 2700 nm, depending on the material and design (e.g., zero-order or multi-order).
Retardance Accuracy
The precision of the phase shift introduced by the waveplate is crucial. For high-performance applications, retardance accuracy can be as precise as <λ/100 for zero-order waveplates. This ensures minimal deviation from the ideal half-wave retardance.
