Minimum angle of resolution of eye
WebThe first minimum is at an angle of θ = 1.22λ/D θ = 1.22 λ / D, so that two point objects are just resolvable if they are separated by the angle θ = 1.22 θ = 1.22 λ D, λ D, where λ λ is the wavelength of light (or other electromagnetic radiation) and D D is the diameter of the aperture, lens, mirror, etc., with which the two objects are observed. WebA logMAR chart (Logarithm of the Minimum Angle of Resolution) is a chart consisting of rows of letters that is used by ophthalmologists, orthoptists, optometrists, and vision scientists to estimate visual acuity. The chart was developed at the National Vision Research Institute of Australia in 1976, and is designed to enable a more accurate …

WebIt follows that the NAs of both the objective and the condenser should be as high as possible for maximum resolution. In the case that both NAs are the same, the equation may be reduced to: The practical limit for is about 70°. In an air objective or condenser, this gives a maximum NA of 0.95.
