An Achromatic Doublet Lens, also referred to as an achromat, typically consists of two optical components cemented together, The achromatic design also helps minimize spherical aberrations. In comparison to a singlet lens, or singlet for short, which only consists of a single piece of glass, the additional design freedom provided by using a doublet design allows for further optimization of performance. Therefore, an achromatic doublet lens will have noticeable advantages over a comparable diameter and focal length singlet.
We can provide customized achromatic doublet lenses to meet your requirements or edge stock lenses for quick turnaround, please inquire.
