Lighted Stand Magnifier
This is a fresnel magnifier. It is not made to be as good of detail as a smaller moulded lens magnifier. It allows a small amount of magnification over a whole page. Regular ground lenses can not do this for physics reasons. Fresnel prisms are all similar in quality and not as good of quality as ground lenses. But, they are large.This is an easily portable unit with LED lighting. It costs much much less than aspheric lenses which have higher magnification, and smaller field. There are better more solid units than this one, but they cost $200 or so. Do not buy if you are expecting a unit that will last years. Under usual use, this unit may last one year.
