Hi all, just a basic theory question. To increase the depth of field on a binocular microscope (the distance between the lenses and the work in my case to be greater to get my hand underneath better), is that accomplished by getting different lenses in a great magnification or of lesser magnification? Mine are currently a wide field 10X-20X on an Amscope microscope.
Essentially I wish I had more working distance, as my hand cannot fit completely under the scope as I'd wish with a graver at a high angle and have the work be in focus. I can raise the scope just fine to get my big paws under but I've lost my focus at that point. I have about 4" of working space at furthest in focus zoom. I hope I'm making sense, I just wondered if a different lens would give me a greater length or if it's the design of the scope and its limiting factors. Thanks a bunch!
