Smaller, Cheaper, Higher Quality: Design Your Next Lens with a Forbes Freeform Surface

The challenges of today’s optical designs require sophisticated and precise non-spherical surface shapes. A new surface formulation specified by G.W. Forbes provides designers with a “freeform” surface where the coefficients are orthogonal (similar to Zernikes), but in addition, provide insight and control over the manufacturability of the surface. These attributes can improve the design process and lower the manufacturing costs for the components that use these surfaces. 

A CODE V surface using the Forbes Freeform formulation is available as a User-Defined Surface, which you can download from the Customer Support Portal.

For background on this freeform surface formulation, see:

G. W. Forbes, “Characterizing the shape of freeform optics,” Opt. Express 20, 2483-2499 (2012).

CODE V Glass Catalog Updates Available for Download

Updates to the CODE V material database, including the Hikari, Hoya, and Ohara optical glass catalogs, are now available for download from Download links and installation instructions can be found on this page. For information about glasses affected by this update, refer to the History of CODE V Glass Database Changes on our website.

Please note that the glass catalog files are not compatible with CODE V version 11.0 or earlier.
