Achromatic lenses are a combination of a positive low refractive index (corona crown ) and negative high refractive index (flint). Compared with monolithic singlet lens the doublet design can provide users with additional design freedom and further optimize the performance of the lens. Therefore, the advantages of achromatic lenses are more significant than those of single lenses with equal diameter and focal length.
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. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses.

The usage of Achromatic lenses
Achromatic lenses are designed to specifically function within the infrared, visible,or ultra-violet wavelength ranges,and they are not symmetric devices.
They must be installed with the correct front-to-back orientation (thicker element usually faces the eyes) if installed incorrectly.with the lens orientation installed backwards the result will be extensive distortion and aberration.Optical glued lens are supplied coated or with a single layer anti-reflection coating suitable for the visible (400 - 600 nm) or the near infra-red (600 – 1200 nm).
The types of achromatic lens
An achromatic lens comes in a variety of configurations, most notably, positive, negative, triplet, and aspherized. It is important to note that it can be a doublet (two elements) or triplet (three elements); the number of elements is not related to the number of rays for which it corrects. In other words, an achromatic lens designed for visible wavelengths corrects for red and blue, independent of it being a doublet or triplet configuration.
We can offer custom plano convex lenses to meet your requirements or alternatively edge stock lenses for a quick turnaround.
