The optimal ratio of the magnification factor and the viewing angle is considered to be the magnification factor of the object from 5 to 7 times. Depending on the degree of magnification, magnifiers are subdivided into devices with strong or weak approximation.
- Product design . A magnifying glass alone is not enough for the convenience of its use, and a certain holding structure is attached to it. Thanks to various design models, the magnifier has become very convenient to use. In retail chains, you can now find a wide variety of types of structures: on a bracket, on a flexible holder, on a stand, on a clothespin. There are long-handled magnifiers, headlamp options, table or floor models, cord magnifiers, keychain pocket magnifiers, and so on.
- Equipped with lighting . To improve the quality of the view and when working with poor lighting levels, an illuminated magnifier is used. LEDs are most often used for backlighting. Illuminated magnifiers are in great demand; they are used in medicine and cosmetology, radio engineering and microelectronics, in the jewelry industry, the banking sector, and in everyday life.
- Lens material . Nowadays, lenses made of glass, plastic or acrylic polymers are widely used. The most budgetary option is a plastic magnifying glass, but this material is very unstable to mechanical stress and various scratches quickly appear on it. The most expensive and valuable lens material is glass. Of course, it will not withstand a fall from a height onto a solid foundation - a concrete floor or asphalt, but minor minor damage is not afraid of it. In the mid-priced category, there is an acrylic polymer that is more durable than conventional plastic, but inferior in quality to the properties of lenses made of glass.
