WebNegative Achromats -- L-AON003. from Ross Optical Industries. Negative Achromats consist of two optical components, a crown and a flint glass lens, cemented together. The crown is usually a bi-concave lens. As is true to all Achromats, they are corrected for color and on-axis spherical aberration. They are used predominantly to extend focal ... The shape of the heads used can vary. The most common head shapes are: A sphere is the ideal shape for a head, because the stresses are distributed evenly through the material of the head. The radius (r) of the head equals the radius of the cylindrical part of the vessel. This is also called an elliptical head. The shape of this head is more economic…
