The Donegan classic magnifier is a hand-held magnifier that has a round lens with a wide rim to protect the lens surfaces, and is available in a variety of lens width sizes and multiple magnification powers (X) at specified focal lengths, or distance from object. This magnifier enhances the size and resolution of an object or image, and is commonly used for a variety of applications such as dermatology, fly-tying, jewelry-making, watch-making, needlework, electronic inspection, book-reading, print inspection, and stamp-collecting.
| This handheld magnifier features a round-shaped body with a wide rim to protect the lens surface, and has an extended handle for gripping. It has a round, optical-grade lens (available in a variety of width sizes) that has been ground and polished into a prismatic lens, and is aspheric to produce a sharp image to the edge of the lens for less distortion. It is available in multiple magnification powers (X) at specified focal lengths, or distance from object. The magnifier weighs approximately 0.333 to 0.667 lbs., and has a one-year limited warranty. Diopter (D) is a technical term for the measurement of the light curvature and thickness of a lens. A dioptric number and a magnification number are not the same thing. Diopter strength represents a specific magnification power (X). For example, a 5-diopter provides 2.5X magnification (at a distance of 8”). The higher the diopter, the more magnification a lens can provide. As magnification increases, distance to the object (focal length), and field of view (diameter, or narrowness of view) decrease. Magnifiers and prescription eyeglasses have a diopter value, such as 1.5 or 2. The dioptric strength of an accessory lens, such as prescription eyeglasses or an eye loupe, must be added to the dioptric strength of the magnifier to calculate total magnification.
