WebAperture Diameter = 20 mm. We know the formula to find out the Angular Resolution is θ = 1.22 * λ / d. Substituing the known parameters in the above formula we have the equation as follows. θ = 1.22 * 150nm / 20mm. Simplifying the equation further we get the value of angular resolution as θ = 0.000524 degrees.
