| Term (EN) | coherence length |
|---|
| Definition (EN) | The propagation distance over which propagating optical radiation may be considered to be coherent radiation.
Note. — If the spectral linewidth of the source is ∆λ and the central wavelength is λ0, the coherence length in a medium of refractive index n is approximately λ02/n.∆λ. |

| Term (SR) | dužina koherentnosti |
|---|
| Definition (SR) | Dužina na kojoj se prostire optičko zračenje koje se može smatrati koherentnim značenjem.
Napomena — Ako širina spektra izvora iznosi ∆λ, a centralna talasna dužina λ0, tada koherentna dužina u medijumu indeksa prelamanja n, približno iznosi λ02/n.∆λ. |
