Re: SMS Baden Fire Control

Just to recap, neither the Germans nor the British made use of gyro stabilization for the main guns at Jutland, the British because they didn't have it yet and the Germans because theirs were prototypes that simply didn't function properly yet, correct? By the time of the SMS Baden most German capit...

Re: British v German rangefinders

Still a completely inaccurate way to gauge the ratio of coated vs non coated optics made, esp. as all evidence available points towards the Heer recieving a lot of coated optics as well. If regular mass produced army Dienstglasses were coated, sometimes both inside & out, then already there you have...

Re: British v German rangefinders

Problem with that claim is that many German rifle scopes were coated during the war (primarily Hensoldt), as were many cameras and army field glasses, of which there is plenty of proof - incl. the links you provided yourself. To claim that only 1 in 40 were coated is pure conjecture based on nothing...

Re: British v German rangefinders

I've provided abundant data to prove that the vast majority of German binoculars, and other WW2 optics, were uncoated. But you haven't? Even your own sources prove that the most common German optical equipment, the common grunts Dienstglass, were coated in huge numbers. Also all German tank optics ...

You didn't prove that at all, infact you disproved it with your own link. There are plenty of coated 1940 dated Dienstglass out there, as well as plenty of coated telescopes from the late 30's.

Re: British v German rangefinders

Most German military optics were uncoated, as were most Allied Optics. This information is widely available, and all you have to do is look for it: "Although some Zeiss Kriegsmarine 6X30’s did have coated optics, the German Army Dienstglas did not ." https://www.flickr.com/photos/binocwpg/751668488...

Re: British v German rangefinders

The person on that website is mistaken, he brings no source to the table either :) According to most sources most German optical equipment was coated after 1938 (of which there is plenty of evidence), incl. most army & luftwaffe binocs as well as rifle telescopes - heck even perscription glasses. On...

Re: British v German rangefinders

I don't think you understand basic optical principles. https://mhcocm.wordpress.com/2011/12/28/a-brief-history-of-optical-coatings/ You don't have to look very hard to discover that antireflective coatings were in use prior to 1935. and Zeiss has no monopoly on this technology, before or after WW2....

Re: British v German rangefinders

The effects are not identical though, some coatings and layering techniques work better than others. The German AR coatings provided an improvement pr. lens of over 80%. The below are a few quotes from a report to the Allied supreme commander (Roosevelt) in March 1945: "Our sight reticule is okay, ...

Re: British v German rangefinders

Yeah I read it, but again there was apparently a great difference in the effectiveness of the coatings and how they were applied, esp. when combined with special made lenses. Also far from as many Allied optical devices were applied with anti reflective coatings as were German devices. The Germans ...

Re: British v German rangefinders

Both the UK (Barr and Stroud) and USA ( Baush and Lomb) introduced coated optics in the late 1930s. They were apparently not the same as the anti reflective coatings by Zeiss which were a closely guarded secret until the end of the war as far as I have read. It's true that the use of lens coatings ...

Re: British v German rangefinders

Wouldn't the German use of coated optics also constitute a significant advantage? According to what I've read the coatings almost doubled the light gathering properties of each lens, allowing the Germans to make larger optical equipment with more lenses without any loss in clarity or brightness of i...
