How do I determine the size of the blades/leaves on a mechanical iris? Answered

Can someone please tell me? I want to know if it's a certain percentage of the base size depending on how many leaves I need and if so, what is the formula? thanks.

Your most definitive answers would come from doing a thorough google search and even a trip to the library.

Overlap of leaves is probably in the area of a 5-10% over-width, although that would be dependent on the quality of the mfg, fit, and intended application.

Further than that I can't say offhand. If it were me, I'd be consulting books, themselves pointed to by the general search "iris mechanics" or similar terms
