An apochromatic lens, or APO lens, is a camera lens that corrects chromatic and spherical aberration better than achromat lenses. The term "apochromatic" comes from the Greek word ἀπό-, which means "free from" or "away from".
APO lenses have several advantages over achromat lenses, including:
Color correction: APO lenses correct color defects, resulting in images with fewer or no color fringes at high-contrast edges.
Image quality: APO lenses produce sharper images with improved color contrast.
Eye strain: APO lenses can reduce eye strain and allow for longer periods of use.
Numerical aperture: APO lenses often have higher numerical apertures than achromat lenses for a given magnification.
APO lenses work by concentrating the red, green, and blue wavelengths of light into a fine point in the center of the lens
