Retardation ↔ Phase Shift calculator
Convert waveplate retardation in nm to phase and wavelength fraction.
Category: Polarization
Formula: φ = 2π · Γ/λ (rad)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Retardation Γ | Gamma | nm | 137.5 |
| Wavelength λ | lam | nm | 550 |
Result with the default inputs
- λ fraction: 0.25 λ
- Phase: 90 °
- Phase: 1.5708 rad
Open it with your own values: put each input in the address as a parameter, for example /calculators/retardation-phase-shift?Gamma=137.5. A unit other than the listed one goes in <parameter>_unit.
