WebTo calculate the Critical Angle, first determine the N.A. (Numerical Aperture).The N.A. of any glass combination may be calculated as follows: (where N1= the index of refraction of the core glass), and N2= (the index of refraction of the cladding glass): For example, taking 1.62 for N1 and 1.52 for N2 , we find the NA to be .56. WebConsidering green light around 500 nm and a NA of 1, the Abbe limit is roughly (0.25 μm), which is small compared to most biological cells (1 μm to 100 μm), but large compared to viruses (100 nm), proteins (10 nm) and less complex molecules (1 nm). To increase the resolution, shorter wavelengths can be used such as UV and X-ray microscopes. diary\\u0027s wm https://mimounted.com
