Hi Omid,
I have now looked more closely to your patent. You have described exactly what Deon Optics has realized in their March Tactical FFP scopes.
It's so simple!!! I wish the European manufacturers would adopt it and go back to FFP.
Hi Fuchs,
Yes, the concept is very simple indeed. But as you noted it is largely unknown to the manufacturers. They are all busy creating ever more complicated reticles and ever more zoon range.. The more hashes or dots or grids a reticle has, the better it sells.
This topic is related to discussing FFP vs SFP for a dangerous game rifle. I feel that there is a lot more that you and I can discuss and explore about rifle scopes.. We might want to create a separate topic for a deeper and more general discussion.

Regarding benefits of large exit pupil (even larger than 7mm and even for use during daylight), I agree with what Fuchs said. We are not talking about gathering light here. It is about providing a large "eye box" behind the eye piece. The eye box is the area that you can position your eye and see the full field of view. A large exit pupil (10mm or more) leads to a much larger eye box. This makes it very easy to position your eye behind the scope and, in a way, the scope becomes as "fast" as a red-dot sight. This is very good feature for fast, off-hand shots or for acquiring the target after the first shot.
