How to Use the Calculator

  1. Enter the wavelength of light in meters in the "Wavelength of Light (λ)" field.
  2. Enter the aperture size in meters in the "Aperture Size (D)" field.
  3. Click the "Calculate" button to compute the resolution power.
  4. The result will be displayed in the "Result" field.

Understanding the Formula

The resolution power of an optical system is determined by the wavelength of light and the aperture size, as given by the formula:

Resolution = 1.22 × λ / D

Where:

  • λ is the wavelength of light (in meters)
  • D is the aperture size (in meters)

This formula is derived from the Rayleigh criterion, which describes the limit of resolution for a circular aperture.
