Celor lens

A Celor lens (also known as a symmetric dialyte)^[1] is a highly corrected lens of the Dialyt type, designed for process photography, involving reproduction at or near 1:1 scale.

It was developed in 1898 by Emil von Hoegh, an optical designer working for the German company Goerz.^[1]^[2]
