text: – Stands for High Refractive Index lens, designed to reduce field curvature and spherical aberrations.
text: It is worth noting that aberrations may be also be spherical (i.e. the result of less-than-perfect lens curvature), though correcting these is much more complex and not necessarily a job for a mere concave lens.
text: Stands for High Refractive Index lens, designed to reduce field curvature and spherical aberrations.
text: The front lens is well corrected for spherical aberrations but introduces coma.
text: In practice, only special glass types can be used to make this lens if it is to correct for spherical aberration and/or coma.
text: Early attempts at making aspheric lenses to correct spherical aberration were made by René Descartes in the 1620s, and by Christiaan Huygens in the 1670s; the cross-section of the shape devised by Descartes for this purpose is known as a Cartesian oval.
text: Soft focus lenses introduce spherical aberration deliberately into the optical formula for an ethereal effect considered pleasing, and flattering to subjects with less than perfect complexions.
