Beam Pointing Stability calculator
Lateral beam wander from angular drift over a propagation distance.
Category: Optomechanics
Formula: Δx = θ · L
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Pointing drift | th | deg | 0.001 |
| Distance | L | m | 1 |
Result with the default inputs
- Lateral shift: 17.4533 µm
- Drift: 17.4533 µrad
Open it with your own values: put each input in the address as a parameter, for example /calculators/beam-pointing-stability?th=0.001. A unit other than the listed one goes in <parameter>_unit.
