WebFor a lens to be achromatic the focal length for red light (F R) must be the same as that for blue light (F B). As with the achromatic prism this can be produced by using a 'doublet' made of two thin lenses of different refractive indices (Figure 4). For blue light: 1/F B = 1/f B + 1/f B ' For red light: 1/F R = 1/f R + 1/f R ' and also we have ...
