Optical Unit

The Optical Unit is a dimensionless units of length used in optical microscopy. Because every diffraction limited system have their resolution proportional to wavelength / NA, it is convenient for comparison to use this unit. There are actually 2 units, one "axial" (along the optical axis of the objective) and one "radial".

Equation

where :

  • is the refractive index
  • is the wavelength
  • the beam conus angle
  • is the total magnification ( is 1 if you want the size in the sample)

Note : = numerical aperture
