Angular Resolution Calculator:Do you want to know how to calculate a lens's angular resolution but aren't sure which formula to use? You don't need to look any further than the Angular Resolution Calculator. Learn what Angular Resolution is, how to calculate it using a formula, and how to calculate Angular Resolution step by step.
Rayleigh criteria is also known as angular resolution.Lord Rayleigh, a well-known scientist, proposed an empirical angular resolution formula is given by the ratio of the wavelength of the radiation(l) divided by the telescope diameter(d) to determines the angular resolution: q = l/D .
The Angular resolution formula: θ = 1.22*λ/d
The above formula is based on the diffraction grating principle. When the major diffraction maximum of one image coincides with the initial minimum of the other, two light sources are said to be resolved.

The following is the procedure on how to use Angular Resolution Calculator to quickly determine the Angular Resolution. They are mentioned below
Question 1: If the wavelength of light is 100nm and the aperture diameter is 30 mm, what is the lens' Angular Resolution?
Consider the above problem and We have the inputs as
Wavelength of Light λ = 100 nm
Aperture Diameter = 30 mm
By converting the wavelength => 150 "nm" to "meter", then
λ = 1e-07 nm
λ =1.0000000000000001*10-07) meter
We know the formula to find out the Angular Resolution is θ = 1.22 * λ / d
By Substituting the known parameters in the above formula we have the equation as follows
Resolution = (1.22 * 1.0000000000000001*10-07) / 30
Resolution = 4.066667*10-09 radian
Therefore, The angular resolution as θ = 4.066667*10-09 radian
1. What is the concept of Angular Resolution?
The ability of an optical equipment to differentiate two objects separated by a tiny angular distance is termed as angular resolution.
2.What do you mean by Rayleigh criterion?
Rayleigh criteria is a concept that describes angular resolution.Lord Rayleigh, a well-known scientist, proposed an empirical angular resolution formula:
3. What is the formula for calculating angular resolution?
The ratio of the wavelength, l, of the radiation divided by the telescope diameter, D, determines the angular resolution: q = l/D.The resolving capacity is derived by the diameter, whereas the light gathering power is determined by the area of the main element (the objective). 0.25 * wavelength (microns) / telescope diameter = angular resolution (arcsec) (m).
The Angular resolution formula:θ=1.22*λ/d
4. What are the Angular Resolution Units?
Angular resolution units includes Radians, Degrees, Gradians, Minutes of Arc, Seconds of Arc, Milliradians, Microradians, and so on.
5. What is the Human Eye's Angular Resolution?
The human eye's angular resolution is 0.02° or 0.0003 radians.
