The legendary Beta-Screen magnifiers of the Betamag series in 20x magnification

In spite of its 20x magnification this lens offers a 6 mm field of view when positioned against the eye. At a distance of 10 centimetres it is still approx. 2 mm and at 20 centimetres approx. 1 mm. The lenses have an anti-reflex coating. The optical system consists of three lenses subdivided into two groups.
The lens can be focussed initially by moving the it close to the eye and then turning the thread to the right distance. The lens can then be arrested with the counter-ring present on the thread. Then hold the lens at the optimum distance for the user or move your eye away until the desired distance is reached. The lens can be folded into a case for protection during transport.
The colour-corrected lenses in the Beta magnifiers is only one of the reasons for their extreme popularity, because it it possible to clearly recognize the individual halftone dots at a distance of 20 centimetres. A further major advantage is that the increased distance between the eye and lens prevents shadows falling on the object to be inspected. These magnifiers are equipped with a special optical system making them egronomical and easy on the eye.
