On the chromatic aberration of microlenses
... To investigate an achromatic design for a microlens we fix a diameter. Then to allow comparisons a wavelength of reference fixing Zp is required. It is now possible to plot the relative variations of this Zp against the wavelength of a defined spectrum. For example, Fig. 9 shows the variations as f ...
