I've not seen them with a variable iris, only an open/close shutter, but

or

would be worth asking. Professional optics components tend to be expensive.
You might find a cheap lens that has the right control for use on CCTV
cameras, in which case I suspect taking the lens apart and removing the
glass might be a cheap alternative.
An ex-collegue of mine developed a variable shutter/iris as part of his
PhD. For the application, there was no commerical alternative - money
was no object, but he had some rather exacting requirements.
His PhD thesis is online
