Periscope Question...

U-48Kriegsmarine · 10-15-09, 05:17 PM

I just must know, were the German attack periscopes offer a circular, or rectangular view? I've seen mods offering them both, but what is real? I currently use the stock circular view, but I'm thinking about gioing the square a try.

Thanks, Dave

seeing that the viewing reticle was round... i would think that the image your eye would see would be round as well

Ive seen video...it was round.

I think the moders get the idea from the square tip at the surface

Circular always!!

Someone (I think it was "Church") long ago came up with the idea of doing a rectangular one, by looking at the EXTERNAL vertical, rectangular glass in the observation periscope head. In fact, it is rectangular to allow the lense to TILT up and down and still be able to see something (Instead of getting blocked by the metallic part of teh scope head), but the lense that tilts inside is circular, and the exit pupil also.

The field of view you see with your eyes however was cut at the higher and lower part exactly beacuse of that ability to have the lense tilt. I have posted in the past here technical diagrams extracted from an authentic Uboat periscopes manual where you can see the real reticle and field of view. It doesn't match at all what you see in historic film footage, mainly because that film footage is 99% sure FAKED. I have pictures taken through periscopes, and have never seen a reticle as in SH3 or in Das Boot, those seem to come from that unaccurate footage filmed for the Newsreel during war time.
