Шаблон:Infobox lens design 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.

Design

It was developed in 1898 by Emil von Hoegh, as a development of his earlier Dagor lens (1892) designed for the German company Goerz.[1][2] It was originally named the Double Anastigmat Goerz [Dagor] Type B, sold in both Шаблон:F/ and Шаблон:F/ versions; in 1904, the faster Шаблон:F/ version was renamed to the Celor and the Шаблон:F/ version was renamed to the Syntor.[3]Шаблон:Rp

Similar four-element air-spaced symmetric dialyte lenses were released by Steinheil (Unofocal, 1901), Kodak, and Taylor, Taylor & Hobson (Aviar, 1917).[3]Шаблон:Rp
