I had a private message from a ASR member requesting details on where a good visual magnification device can be found. Rather than post the reply privately I made this post for public viewing.
They are sometimes difficult to find. Search for, "loupe." I've seen scientific supply websites sell them, sometimes electronic supply. To get a good one new I guess about ~$50.00 and up to hundreds of dollars.
Keep your eyes open for a parts unit camcorder with glass for parts. Also the earlier consumer saticon tube type or newvicon tube type camcorder with the longer glass lens assembly works sooperb. I mean finding a camcorder compound lens that unthreads and breaks down into multiple lenses for service and cleaning. Remove the front lens assembly, disassemble it, reverse it and look into it backwards and voila a high end loupe magnifier.... I've seen comparible new handhelds go for about $300.00 Canadian but they are rare.
I have also used a stereo microscope for QA/QC work on a articulating arm(Like a lamp arm.) so it can be swung out of the way but kept close at hand. I prefer a good glass handheld magnifier though because it can be moved in more positions and more angles of viewing than a stereo microscope.
