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 clearly and accurately.

At 20x magnification, the field of view is significantly reduced compared to lower magnifications. This means that gemologists must maneuver the loupe carefully to inspect different areas of the gemstone thoroughly. At lower loupe magnifications, such as the most commonly used 10x, field of view is significantly larger, but small details may be less easily visible.
