High-quality and precise magnifying glass with corrected lenses. Our recommendation for 35mm negatives and slides.
The optical system, consisting of two groups of three elements each, offers an absolutely sharp, true-to-color and extremely high-contrast image across the entire viewing area. The image perceived through the magnifying glass is particularly sharp from the center to the edge of the image because the magnifying glass has undergone careful optical correction and deviations and distortions have been eliminated.
Conventional magnifying glasses are only corrected in relation to the center of the image. This magnifying glass is similar to an anastigmatic lens of a camera lens and is manufactured with the same care and precision as one. One aspect in which this magnifying glass differs from the lens of a camera lens is that the effective pupil of the magnifying glass is 25 mm below the upper pole of the magnifying glass, so that a viewer can examine the entire field of view by moving the eyeball and not the head. In addition to classic applications such as image, print and slide inspection or length or distance measurements up to 40 mm, the Anastigmat magnifying glasses 1990-4 (measuring range 60 mm) and 1990-7 (measuring range 40 mm) are used for checking X-ray films or in the field of dermatology, among other things. Wherever a perfect distortion-free and true-color representation is required in addition to a large field of view, the Anastigmat magnifying glass is the ideal tool.
The scales are set in a plastic ring and can be easily removed. The lenses are coated with an anti-reflective coating.

info
In optics, an achromat is a system of two lenses made of glass with different Abbe numbers (different degrees of dispersion).
The system contains a converging lens (usually made of crown glass) and a diverging lens with a smaller Abbe number and thus greater dispersion than the converging lens (usually made of flint glass). This allows the longitudinal chromatic aberration that every simple lens has to be corrected for two wavelengths, i.e. the system has the same focal length for these two colors.
