Hi Luciano,
Looks great! 8" / 203mm objectives makes your design one of the largest bino designs I've heard of. The body of the binocular looks like it doesn't have prisms in its design. Is that what you're planning to use the right angle adapters for?
I'm looking forward to your reports on your project. Kudos!

I will use Matsumoto EMS right angle to this bino .

For 90 degree deviation Matsumoto style system, light hits mirror at 60 degrees, so mirror must be flatter than for a 45 degree incidence Newtonian mirror. Also, design of coating for enhanced aluminum or enhanced silver, or all-dielectric mirror , is different for 60 degree incidence angle than for 45 degree incidence angle. Is it different, between 45 and 60 deg, for simple protected aluminum?

Sure as heck looks like all these angles are cut at 45s?

Hi Ed,
I've tried using two 45 degree image erecting prism diagonals in tandem to recreate a Matsumoto style binocular. When all was arrainged so the image wasn't rotated the final eyepiece angle was 45 degrees not 90. I believe Gordon's correct about the 60 degree (or 30 depending how you think about the geometry) being needed to end up with a 90 degree binocular.
As far as Gordons other points, the mirrors do need to be a bit longer/bigger than a 45 degree mirror. I don't know about flatter. There are some awfully good quality 45 degree newtonian mirrors that would be plenty large enough for this application.
Are the coating issues for a mirror the same as those of a lens? I wasn't aware that anti-reflection coatings are used on mirrors. Sounds a little anti-productive to me. Perhaps Gordon could elaborate a bit about what he meant. For all I know there are coating issues for mirrors used at differant angles.
Peter
Edit- As Ed mentions below, antireflection coatings weren't part of Gordons statement. My apologies

Gordon didn't mention any anti-reflection coatings. I'm sure he's referring to silvering or aluminizing.

Thanks, perhaps Gordon was just asking if there is any difference in designing a 60 degree vs a 45 degree mirror.
I would be interested in finding out if a dielectric mirror would work as well as a silver or aluminum mirror for this type of application. Other than cost, of course.
