WebThe Airy disk (∅Airy Disk) ( ∅ Airy Disk), or minimum spot size, can be estimated using the f/# and wavelength (λ): Figure 1: Diffraction increases as the imaging lens iris is closed (f/# increases). The top lens is set at f/2.8; the bottom lens is at f/8. Table 1 shows the Airy disk diameter for different f/#s using green light (520nm). WebUsing short wavelengths helps to salvage some of this resolution. ... As the derivation in Equation 3 shows, depth of focus, $\delta $, is heavily dependent on the number of pixels or pixel count, $ p $, and has little to do with array or pixel size, $ s $.
