Electro-Optic Deflection calculator
Deflection angle from EO crystal under applied voltage.
Category: Scanning
Formula: θ = n³·r·(L/d)·(V/d) / 2
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Index n | n | 2.2 | |
| EO coef. r | r | pm/V | 30 |
| Length L | L | mm | 20 |
| Aperture d | d | mm | 2 |
| Voltage | V | V | 1000 |
Result with the default inputs
- Deflection: 0.7986 mrad
- Deflection: 0.0458 °
Open it with your own values: put each input in the address as a parameter, for example /calculators/electro-optic-deflection?n=2.2. A unit other than the listed one goes in <parameter>_unit.
