Kinematic Mount Resolution calculator
Angular tilt per rev/turn from screw pitch and lever arm.
Category: Optomechanics
Formula: Δθ = pitch / (arm) per full turn
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Threads per inch | TPI | 100 | |
| Lever arm | arm | mm | 25.4 |
| Knob fraction | frac | 0.01 |
Result with the default inputs
- Per full turn: 10 mrad
- Per 0.01 turn: 100 µrad
Open it with your own values: put each input in the address as a parameter, for example /calculators/kinematic-mount-resolution?TPI=100. A unit other than the listed one goes in <parameter>_unit.
