Large Rectangular Dome Magnifier 3.75" 3.75x 10D Magnifying Dome

DR-3.75 Large Rectangular Dome Magnifier – 4x Power Reading & Chart Magnifier

The DR-3.75 Rectangular Dome Magnifier is a professional-grade, easy-to-use reading stand magnifier designed for clarity, control, and comfort. Featuring 4x (10 diopter) magnification and a large 3.75" wide viewing area, this magnifier delivers sharp, distortion-free enlargement for documents, charts, and detailed plans.

Its rectangular shape with two flat sides makes it easier to hold and guide smoothly along a horizontal reading path—ideal for newspapers, books, and technical documents. The unique design combines the natural illumination of a bright-field dome magnifier with the optical superiority of a thick aspheric lens for enhanced clarity and contrast.

To protect delicate surfaces, the plano base is raised 0.5mm, helping prevent scratching while allowing the magnifier to glide effortlessly over printed materials.
