Magnifiers Are Devices Used To Enlarge The Visual Appearance Of An Object Or Image. Magnifiers Come In A Variety Of Styles Such As Hand-Held, Headband, Standing, Clip-On, Eye Loupe, And Those That Hang In A Necklace Form, Or Fit In A Trouser Pocket. Magnifiers Are Commonly Made Of Plastic Or Glass. They Can Have One Or More Lenses With Varying Magnification Abilities, And Can Have A Binocular Configuration With A Single Lens, Or Two Separate Lenses. They Are Sometimes Used With Led Or Fluorescent Light Sources To Help Control Viewing Capabilities. Magnifier Ability Is Often Expressed As Magnification At A Specific Length. For Example, 1.75X At 14 Means That When A Magnifier Is Held At 14 From A Viewers Eyes, The Object Will Be Magnified 1.75 Times (X) Its Actual Size. As Magnification Increases, Viewing Areas And Focal Length Decrease. Magnifiers Sometimes Have A Diopter Number, Expressed As + Or -D, Which Is A Measurement Of Strength (Or Power) Of The Lens. Some Magnifiers Are Marked With A Dioptric Number On The Lens. A High Diopter Number Has A Higher Magnification Than A Low Diopter Number. Aspheric Magnifiers, Unlike Spheric Magnifiers, Produce A Sharp Image To The Edge Of The Lens For Less Distortion. Magnifiers Are Widely Used In Jewelry Inspection And Fabrication, Watch-Making, Needlework, Artwork, Fly-Tying, Electrical Inspection, Reading, Print Inspection, And Stamp-Collecting.Donegan Optical Manufactures Precision Visual Devices Such As Magnifiers And Optical Loupes.
