Calculation Formula

θ = 1.22 * (λ / D)

Where:
θ = Angular Resolution (in radians)
λ = Wavelength of light (in meters)
D = Aperture Diameter (in meters)

Result

Learn how to use the Angular Resolution Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the wavelength of light in meters in the "Wavelength (λ)" field.
  2. Enter the diameter of the aperture in meters in the "Aperture Diameter (D)" field.
  3. Click the "Calculate" button to compute the angular resolution.
  4. The result will be displayed in radians.

Working Principle

The angular resolution (θ) is the minimum angular separation between two points that can be resolved by an optical system. It is given by the formula θ = 1.22 * (λ / D), where λ is the wavelength of light and D is the diameter of the aperture. This formula is derived from the diffraction limit of resolution.
