Rayleigh Resolution calculator
Smallest resolvable feature for a microscope objective.
Category: Diffraction
Formula: r = 0.6098·λ/NA (j₁,₁/2π ≈ 0.61)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Wavelength | lam | nm | 550 |
| NA | NA | 0.65 |
Result with the default inputs
- Resolution: 516.0142 nm
- Abbe limit: 423.0769 nm
Open it with your own values: put each input in the address as a parameter, for example /calculators/rayleigh-resolution?lam=550. A unit other than the listed one goes in <parameter>_unit.
