Achromatic Triplet Lenses for Advanced Optical Systems

Achromatic Triplet Lenses are designed with three carefully selected optical glass elements to achieve enhanced chromatic aberration correction and improved optical performance. By combining glasses with different refractive indices and dispersion characteristics, triplet lenses can reduce color fringing, improve image contrast, and deliver more accurate focusing across multiple wavelengths.

Compared with achromatic doublet lenses, achromatic triplets provide better correction of residual chromatic aberration and spherical aberration. They are commonly used in applications where high image quality, compact optical design, and stable broadband performance are required.

Realpoo Optics provides custom achromatic triplet lenses for imaging systems, laser optics, microscopes, telescopes, collimators, medical devices, and optical measurement instruments. We support OEM production based on customer drawings, samples, optical design files, or specific application requirements.
