I am trying to learn about Leitz/Leica coatings and their introduction, especially versus Zeiss.
My tentative matrix is this:
Any improvements on this are very welcome, as are additions. It appears that Leica are either VERY tight-lipped about their coatings, or just less well researched by users in comparison to the Zeiss afficionadoes.
Can anyone add more specific introduction dates of coatings to the different series, ie. Noctivid, Ultravid and Trinovid?
My tentative matrix is this:
1989 | P40® | phase correction (20/25 Trinnies from 1998) |
2003 | HDC® | transmission multi-coating (High Durability Coating) |
Nov. 2010 | AquaDura® | hydrophobic coating |
2012? | HLS® | dielectric coating (HighLux-System) |
