	The number of nizkodispersnyh elements $(from 1 to 7) number of applied in optical lens design (nizkodispersnyh). Variance is called optical phenomenon, when during the passage of the light flux from the environment and on Wednesday b (for example, from air into water) beams of light of different colors are refracted at different angles. Beams during light flow through the lens has refracted on the surfaces of the lens the lens, then the light hits on fotomatricu or film. On the output image, because of the dispersion of light, you might have unwanted color fringing. This kind of distortion, chromatic aberrations referred to specialists. Lenses low variance are made from special glass, it refracts light in the same way with any wavelength. Often than optical lens scheme applies more nizkodispersnyh elements, so it is less susceptible to the negative effects of chromatic aberration.$	2
