Apochromatic triplet

Apochromatic Triplet

In fact, the best quality lens available, although a distinction must be made here of which glass type the triplet lens consists of.

ED or Fluorite. ED is an excellent lens with hardly any color error. Fluorite is even better, but also much more expensive.
