I already posted this question, but it does not appear in the list of Latest Forum Threads.
Fortunately I cross referenced it in another thread, and Solar Eagle was kind enough to PM me to say that the thread will not allow replies. (Without that I probably would not have noticed that it does not appear in the Latest Forum Threads, and would just wondered why I had had no replies)
Anyway maybe I broke some CR4 rules regarding advertisements (although the post has not been deleted
) so I will just précis it here.
I am thinking of buying some dental loupes they are used by dentists to give 3.5 x magnification at 420mm with a good depth of vision. I suspect that because they are designed for a focal distance of 420mm, then if I used them on top of cheap reading glasses I could get much more magnification at a much shorter focal distance.
Alternatively, there are magnifiers with interchangeable lenses (called EEEKit) that give from 1 to 14 times magnification, but I'm not sure that they will have the same 3D depth of field.
Solar was also kind enough to point me to some digital microscopes with a small LCD display: I've got one of those, they're great for some jobs but they do not have any depth of field.
