Micro Achromatic Lenses for Compact Optical Systems

Micro Achromatic Lenses are designed for applications that require small lens size, accurate focusing, and reduced chromatic aberration. By combining optical glass materials with different dispersion properties, micro achromatic lenses help bring different wavelengths closer to the same focal point, improving image sharpness and reducing color fringing.

Compared with micro singlet lenses, micro achromatic lenses provide better optical correction and more stable imaging performance. They are especially suitable for compact optical instruments, miniature imaging systems, medical optical devices, and precision optical modules where space is limited but image quality is important.

Realpoo Optics provides custom micro achromatic lenses according to customer drawings, samples, optical design files, or specific application requirements. We can customize lens diameter, focal length, coating, material, edge treatment, and assembly structure.
