Ross Optical Bi-Concave Lenses
Compare
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 ...

Freeforms are optical shapes or optical surfaces that are designed with little to no symmetry. Manufacturing a freeform is similar to that of a highly complex asphere; surface form and local slope change are all factors that influence the complexity of the shape and the manufacturing process used.

Lenses in high-index glass (n = 1.785) have only 55% of the spherical aberration of equivalent BK7 lenses, and can be very efficiently AR coated with a single-layer coating. Beam expanders etc. can therefore be made with near diffraction-limited performance and very high transmittance and suitable for high powers, having no cemented ...

Negative lenses form a reduced virtual image of a real object (as in door viewers).  However, if inserted in a system such as a microscope upstream from an image plane, the image will be magnified and projected further. Such a lens is known in microscopy as a tube-length correction lens and in astronomy as a Barlow lens. We ...
