Achromatic Lens(Doubel Lenses)
An achromatic lens can be defined as a lens which is made by acombination of two different types of lenses carrying different focal powers in a manner such that the images formed by the light of both the combined lenses are free from chromatic aberration or achromatism.
Description
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. Achromatic Lenses, which are often designed by either cementing two elements together or mounting the two elements in a housing, create smaller spot sizes than comparable singlet lenses.
