resolution distance of light
The effects on resolution of light's wavelength become obvious when calculating the sizes of Airy discs of a certain scope from near infrared to near ultraviolet across the visible spectrum: D=235mm, f=2350mm. d(lambdaNIR) ~ 2.44 * 700nm * 10 = 0.0171mm. d(lambdaR) ~ 2.44 * 620nm * 10 = 0.0151mm.
