Crafts DGL 30 Magnifying Glasses Discovery is a binocular magnifying glass, i.e. a magnifying glass with lenses for two eyes. The magnifier has a spectacle frame so that your hands remain completely free when using it. It is ideal for working with small objects and a detailed study of various objects: watch movements, jewellery, electronic circuit boards, works of art and much more. It is a perfect tool for professional use and a good choice for hobbies that require a practical magnifying glass. Both lenses are made of optical polymer glass. In terms of viewing fine details, this material is no less efficient than standard glass, and its durability can even surpass it. The lenses can be moved left and right along the frame, and if you want to view an object with the naked eye, you can simply flip them up. There are LEDs near the lenses: the illumination produces an extremely bright and even light, allowing you to work even in complete darkness. The lighting angle is adjustable. Powered by batteries. Includes lighting with adjustable angle. 4x CR1620 batteries (not included). Magnification of the lens: 20 x. Lens diameter: 15 mm. Body made of plastic. Spectacle frame made of metal. Colour: blue.
