Ross Optical Steinheil Triplets
The Steinheil triplets are made of a low index crown element cemented in between two identical meniscus flint elements. Specially designed for 1:1 conjugation, they perform well for conjugate ratios up to 5. These lenses make good relay optics for both on- and off-axis application and are often used as eyepieces.

Ross Optical Negative Achromats
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 lengths in combination with positive achromatic ...

Ross Optical Standard Achromats
These lenses consist of two optical elements, usually of crown and flint glass types, cemented together to form an achromatic doublet. Most often, the crown lens is a biconvex positive lens. Due to the difference in refractive indices, chromatic aberration with respect to two selected wavelengths has been corrected. The lenses have ...

Ross Optical Bi-Concave Lenses
Bi-concave lenses have two inward curved surfaces. These lenses have a negative focal length. Our catalog bi-concave lenses have an identical curvature on both sides of the lens and are therefore symmetric. At unit conjugation, coma and distortion are cancelled out due to the symmetry. They are used to diverge incoming light or ...
