Guide: How to choose your Magnifier
The most common questions we receive are about magnification and finding the right level for the task or application. We are frequently asked for a higher power magnifier, one with greater magnification, but also with a large lens.
Indeed the perfect magnifier would have a large lens, provide a wide viewing area, and offer high, distortion-free magnification, as well as being low in cost . However, incorporating all of these features into one unit is not possible. All magnifiers are a compromise between the level of magnification and the size of image which can be seen (called Field of View). This is the case whatever the type of magnifier or manufacturer brand.
Increasing magnification power makes the magnifier less convenient to use as the lens diameter, field of view and working distance all decrease. Usually, it is best to choose low power for reading or viewing larger surfaces and high power for inspecting small areas.
Magnification 3x – 4x, most popular for reading.
Magnifiers of 2x or 3x are most suitable for reading documents, such as the Eschenbach mobilux magnifier 3.5x. For more comfort a stand magnifier can be used such as the Eschenbach Vario, which rests on the surface, or on the document.
However, as eyesight becomes impaired with age and conditions such as macular degeneration, the request for higher magnification increases.
Magnification 5x – 6x, smaller field of view and round lens.
All magnifiers with magnification power above 4x have round lens, not rectangular with a smaller field of view. Magnifiers with 5x only allow to read at best 3 words at a time.
Magnification 7x – 30x, inspection of fine details.
The smaller field of view that comes with a 7x or greater magnification are recommended for inspection of very fine details, such as the range from PEAK. The magnifier rests on the object inspected.
