DM-3 Dome Magnifier 3" Inch diameter (medium size) and 4x magnification, the 3 inch is our most popular size because of its ideal combination of size, field of view, and high magnification. Dome Magnifiers are one of the easiest magnifier types to use, just place the magnifier on a flat surface for 4x magnification ideal for magnifying newspapers, charts, paperwork, books, financial and accounting statements and documents. Simply place the Dome magnifier on the surface and glide across to easily view with 4x magnification, the bottom of dome magnifiers is slightly concave to prevent scratching.
A 3" Dome Magnifier provides a medium sized magnifying area is large enough to magnify specific hard to read areas on documents, technical plans, marine charts, architectural plans, and geological maps. Unlike others our DM-3 uses only optical grade acrylic in our Dome Magnifiers for optimum clarity, scratch resistance, and minimal distortion. Acrylic Dome Magnifiers will not crack and chip like cheaper glass dome magnifiers, and ours also have higher magnification. All Dome Magnifiers are also available with custom corporate engraving for a charge, see photos for example.
