Interferometric Fringes calculator
Fringe spacing from wavelength and crossing angle.
Category: Spectroscopy
Formula: Λ = λ / (2·sin(θ/2))
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| λ | lam | nm | 633 |
| Angle θ | th | ° | 10 |
Result with the default inputs
- Fringe spacing: 3631.4302 nm
- Fringe spacing: 3.6314 µm
Open it with your own values: put each input in the address as a parameter, for example /calculators/interferometric-fringes?lam=633. A unit other than the listed one goes in <parameter>_unit.
