Scanner Angular Range calculator
Linear field of view from scan angle and focal length.
Category: Scanning
Formula: FoV = 2·f·tan(θopt) · θopt = 2·θmech
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Mech. angle | thm | ° | 10 |
| Focal length | f | mm | 100 |
Result with the default inputs
- Optical angle: 20 °
- Linear FoV: 72.794 mm
Open it with your own values: put each input in the address as a parameter, for example /calculators/scanner-angular-range?thm=10. A unit other than the listed one goes in <parameter>_unit.
