Diffraction Grating calculator
Diffraction angle for a grating order.
Category: Diffraction
Formula: d·sin θ = m·λ
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Lines/mm | lpm | 600 | |
| λ | lam | nm | 532 |
| Order m | m | 1 |
Result with the default inputs
- Spacing d: 1666.6667 nm
- Diff. angle: 18.6146 °
Open it with your own values: put each input in the address as a parameter, for example /calculators/diffraction-grating?lpm=600. A unit other than the listed one goes in <parameter>_unit.
