These magnifiers are made of a highly refined achromatic pair of double lenses, ensuring color and shape faithful display. Magnifiers are equipped with replaceable front lenses with steamed measuring patterns, thanks to which, for example, it is possible to measure distances with an accuracy of 0.1 mm. They can also be used for workshop measurement of lengths, angles, radii, holes, pitch of threads, etc. Focusing on the measured shape is performed by a rotating ring on the body of the measuring magnifier. The design of the magnifier enables lateral illumination.
