NEP & Detectivity (D*) calculator
Convert between NEP, area, bandwidth and specific detectivity D*.
Category: Detectors
Formula: D* = √A / NEP (NEP in W/√Hz; = √(A·Δf)/NEP for an NEP in W over Δf)
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| NEP | NEP | W/√Hz | 1e-14 |
| Area A | A | mm² | 1 |
| Bandwidth Δf | BW | Hz | 1 |
Result with the default inputs
- D*: 1.0000e+13 cm·√Hz/W
- Min detectable P: 1.0000e-14 W
Open it with your own values: put each input in the address as a parameter, for example /calculators/nep-detectivity-d?NEP=1e-14. A unit other than the listed one goes in <parameter>_unit.
