Delivery time within Germany: 7 - 10 working days
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, provides an absolutely sharp, color-accurate, and extremely high-contrast image across the entire viewing area. The image perceived through the magnifying glass is exceptionally sharp from the center to the edges, as the magnifying glass has undergone careful optical correction to eliminate deviations and distortions.
Conventional magnifying glasses are only corrected with respect 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. One aspect in which this magnifying glass differs from a camera lens is that the effective pupil of the magnifying glass is located 25 mm below the upper pole of the lens, allowing the viewer to examine the entire field of view by moving their eyeball rather than their head. In addition to classic applications such as image, print, and slide inspection, or length and 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, among other things, for checking X-ray films or in the field of dermatology. Wherever a large field of view, a perfect, distortion-free, and color-accurate representation is required, the Anastigmat magnifying glass is the ideal tool.
The scales are encased in a plastic ring and can be easily removed. The lenses are coated with an anti-reflective coating.

info
In optics, an achromat is understood to be a system of two lenses made of glass with different Abbe numbers (different dispersion levels).
The system contains a converging lens (usually made of crown glass) and a diverging lens with a lower Abbe number and therefore stronger dispersion than the converging lens (usually made of flint glass). This allows the longitudinal chromatic aberration inherent in every simple lens to be corrected for two wavelengths; that is, the system has the same focal length for these two colors.
