    There are a couple of different types of binocular loupe the most
    common one is the galilean type which Rio has in their new catalog
    these are very much like a standard loupe in that they have several
    lenses lined up in one axis and give much better quality of
    magnification at a longer focal length than the Optivisor type of
    magnifier. They do have a couple of drawbacks they do tend to create
    some distortion around the periphery of the lens and some spherical
    distortion. 

    There is a second kind of binocular loupe that is the prismatic kind
    they have a similar group of lenses but also include a prism like
    many binoculars this allows a longer distance between elements and
    results in a better quality magnification. These are sold by Zeiss
    they are  much better optically in that the field of view is larger
    and it is much less distorted. however they are much more expensive.
    They cost about as much as a microscope but they have one great
    advantage over a microscope they are always pointed at what you are
    looking at whereas with a microscope you must align your work and
    body to the microscope.  If you only need 4x magnification (about
    equivalent to a #10 Optivisor) I think you will find a set of
    prismatic binocular loupes is much better than a microscope however
    if you need 10X magnification like some high precision engravers or
    stone setters you may want the microscope. 

    I have had a set of Zeiss prismatic loupes for several years now and
    would not part with them for the world. 

    If you are seriously interested in them contact Clemencia Sanchez at
    Zeiss  888.733.2790 they will send you a set to evaluate for 30
    days. 

    Disclaimer I am not connected to Zeiss just a satisfied customer.
