WebAchromatic optics are optical devices or setups which have been optimized such that chromatic aberrations are minimized, such that they can be used in a wide range of wavelengths. Most frequently, this refers to optical lenses or objectives, which are essentially combinations of several lenses. In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends …
