What is Angular Resolution?

Angular resolution is the minimum angle between two points that can be perceived as separate by an optical system, such as a telescope or the human eye. It’s a critical parameter in astronomy, microscopy, and photography, as it affects the level of detail that can be observed or captured. The angular resolution of an optical system depends on the wavelength of light, the diameter of the lens or aperture, and the distance between the objects being observed.

What is Angular Resolution Calculator Website?

The Angular Resolution Calculator website is an online tool designed to calculate the angular resolution of an optical system. This calculator is essential for astronomers, photographers, and researchers who need to determine the minimum distance between objects that can be resolved by their equipment. The website is user-friendly, requiring only two inputs: the wavelength of light and the diameter of the lens or aperture.

How to Use Angular Resolution Calculator Website

Using the Angular Resolution Calculator website is straightforward:

  1. Enter the Wavelength: Select the unit of measurement (nanometers, micrometers, millimeters, centimeters, meters, kilometers, inches, feet, yards, or miles) and enter the wavelength of light.
