Axial Chromatic Aberration calculator
Longitudinal focal shift from Abbe number dispersion.
Category: Aberrations
Formula: Δf ≈ f / V (mm)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Focal length | f | mm | 100 |
| Abbe number V | V | 64 |
Result with the default inputs
- Δf (F to C): 1.5625 mm
- Δf / f: 1.5625%
Open it with your own values: put each input in the address as a parameter, for example /calculators/axial-chromatic-aberration?f=100. A unit other than the listed one goes in <parameter>_unit.
