Category: Materials
Formula: Δn = (dn/dT) · ΔT
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| dn/dT (1/K) | dndt | 0.000011 | |
| ΔT | dT | K | 20 |
| n at T0 | n0 | 1.5168 |
Result with the default inputs
- Δn: 2.200000e-4
- n(T): 1.51702
Open it with your own values: put each input in the address as a parameter, for example /calculators/thermo-optic-shift-dn-dt?dndt=0.000011. A unit other than the listed one goes in <parameter>_unit.
