Telescopes Optics Lens design Triplet

A lens telescope that almost completely corrects chromatic aberration. It consists of three lenses and offers very high optical performance thanks to its design.

Triplet ED Apochromats

Apochromats with three lens elements are also often referred to as triplet apochromats. Only this telescope design can sufficiently correct unwanted chromatic aberration. The secondary spectrum, the residual chromatic aberration, is corrected by different types of glass and refractive indices. The three-lens ED apochromats reduce chromatic aberration almost completely. The image is not only clear and neutral, but also has particularly high contrast.
