I work in a public research institute and on one setup we have the following lens:
It works well and I'd like to replicate the setup, but there is no reference on the lens, not even a brand name. It is C-mount. Can anyone recognize this lens?
It's a pretty old one, It's been on a shelf for years (if not decades). It may not be sold anymore; in this case, can anyone point me out to something equivalent?
