Achromatic Lens XLA-002
Description
An achromatic doublet is a closely spaced cemented combination of positive and negative elements with differing refractive indexes. These elements are chosen so that chromatic aberration is cancelled at two distinct and well-separated wavelengths typically selected to fall in the red and blue portions of the spectrum.
