Precision Aplanats

These Achromats are not only corrected for spherical aberration and axial color as the standard Achromats but also corrected for coma. This combination makes them Aplanatic in nature and allows for better optical performance. They are used as laser focusing objectives and in electro-optical and imaging systems.
