Achromatic Magnifying Lens - 20x Zoom khouribga Approximate Size of 1 piece:Description: Achromatic lenses are designed to minimize chromatic aberration, which occurs due to different wavelengths of light bending at different angles as they pass through a lens. This aberration can cause colored fringes around the edges of objects, compromising clarity and color accuracy. The corrected optics of achromatic lenses enable gemologists to observe fine details such as inclusions, facets, and color zoning within gemstones more
