Hi folks,
Some months back I made transparency photos of Patterson Photo
Resolution targets (or whatever they are called), to test several of my lenses.
Then I was faced with finding a satisfactory means of examining these slides.
I projected them on a screen, but soon gave that up as a method as it
quickly became apparent that my projector lens was not up to the task, and
I could not find a substitute that could reliably be described as being
significantly better. No-body knows, or if they do, aren't telling !!
Dreammoose suggested using a microscope. I *could* ask an old work
colleague if I can invade his lab for this purpose, but I am reluctant to do
so.
An alternative is the amazingly inexpensive pocket microscopes marketed
by Edmund Scientific. Two powers - 20?x and 50x.
Does any list member have experience to advise me what range of
magnification I might find suitable for this purpose? I want to count lines per
mm on the slide.
Cheers, Brian
