Actually- I am looking at focusing on a point or specific area of the object plane below the lens. In the attached diagram, say there are three letters w, x and y written on focal plane of the lens of arc length L and focal length F and three observers are looking at it from 3 directions, then all of them should be able to see magnified version of X. W AND Z SHOULD REMAIN HIDDEN EVEN WHEN OBSERVED FROM ANY DIRECTION.

Another way, I am interested in seeing say only 33% or say even 50% of the object plane only from all directions, I want the remaining 66 or 50 % to stay hidden...irrespective of the angle from where I am viewing. Going by the example, I have arc length L of say 10mm so I will define my focal plane a circle having area of π*D2/4= 314/4=7.85 sq mm approx. Now I want my lens to focus only on say "the same" 2 to 3 sq mm area in the middle only and make the other peripheral area hidden when viewed from lens from any direction...

We can say I am looking at system which is opposite of Lenticular Lens. In lenticular lens I see different images from different angles. Here I want same "magnified" image from all the 180 degree angle of view.
