Pixel Resolution calculator

Object-space resolution from sensor pixel pitch.

Category: Imaging

Formula: GSD = p·(u − f)/f (≈ p·u/f for u ≫ f)

Inputs

InputParameterUnitDefault
Pixel pitchpµm3.45
Distanceumm1000
Focal lengthfmm25

Result with the default inputs

  • Object px size: 134.55 µm
  • Object px size: 0.1346 mm

Open it with your own values: put each input in the address as a parameter, for example /calculators/pixel-resolution?p=3.45. A unit other than the listed one goes in <parameter>_unit.
