There are two ways to calculate resolution, the Rayleigh criterion, and the Dawes limit.

The angular resolution is proportional to the ratio of the wavelength, l, of the radiation divided by the telescope diameter: q = l/D. It is the capacity of an image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to separate two objects located at a small angular distance. A single optical telescope may have an angular resolution less than one arcsecond, but astronomical seeing and other atmospheric effects make attaining this very hard. We can also talk about angular area! ). 0000003262 00000 n It follows that the NAs of both the objective and the condenser should be as high as possible for maximum resolution. Answer: First convert all numbers to centimeters, then use the formula to calculate the It is used in optics applied to light waves, in antenna theory applied to radio waves, and in acoustics applied to sound waves. }); This calculator computes the diffraction-limited angular resolution of an optical system, such as a telescope or the human eye. Because of diffraction even an aberration-free optical system images a point source not as a point but as an Airy pattern, whose central area is called the Airy disk. Point-like sources separated by an angle smaller than the angular resolution cannot be resolved. The angular resolution R of a telescope can usually be approximated by where is the wavelength of the observed radiation and D is the diameter of the telescope's objective. The formula to find the Angular Resolution of a telescope is.
