How about the curvature, do you had any ideas on it?

What do you want to know about the curvature? See Curvature - Wikipedia

Hi Genady, can you elaborate more about the angle that you stated? I had a little bit confused on the angle that you mentioned and curvature. Currently manufacturer required us to provide the diameter and curvature information of mirror to create the prototype for us.

1. So, you didn't need an angle from the beginning?

If you did, could you show that angle on your original sketch?

 

2. If it is a circular cylinder, then the curvature would be reciprocal of the circle radius.

Maybe you're talking about a lens rather than a cylinder?

Thank you for reply

1. I need the curvature at the beginning

2. I am not sure whether the cylinder is the shape that is suitable or not as the maximum diameter of cylinder can be build is 1.5 meters only

Sorry, but not enough data given to solve this problem.

Can I know what kind of information that you needed? I will try my best to get it

A sketch of what it is you're talking about, for the starter. The original sketch does not correspond to what you say now.

Understood. But still thank you for your help along this time 

Can someone point me out to the correct answer?

No, because the question was not adequately specified, as the progress of the subsequent discussion shows. 

Thank you for your information
