Input information:

diffraction by a circular aperture |  \naperture radius | 0.2 mm  (millimeters)\nwavelength | 650 nm  (nanometers)


Result:

Rayleigh criterion angle | 0.11356°  (degrees)\n= 1.982 mrad  (milliradians)\n= 0.001982 radians


Equation:

sin(theta_R) = (j_(1, 1) lambda)\/(2 pi a) |  \ntheta_R | Rayleigh criterion angle\na | aperture radius\nlambda | wavelength\n(valid in far-field limit (Fraunhofer diffraction))
