Grating Resolving Power calculator
Spectral resolution R = λ/Δλ from groove density.
Category: Spectroscopy
Formula: R = m·N
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Lines/mm | lpm | 1200 | |
| Width | W | mm | 50 |
| Order m | m | 1 | |
| λ | lam | nm | 550 |
Result with the default inputs
- N grooves: 60000
- Resolving R: 60000
- Δλ: 0.0092 nm
Open it with your own values: put each input in the address as a parameter, for example /calculators/grating-resolving-power?lpm=1200. A unit other than the listed one goes in <parameter>_unit.
