Oslo lens design software 6.6

Lambda Research has announced the latest release of its Oslo lens design software version 6.6.

Oslo 6.6 is now fully compatible with Windows 7 and program improvements include Step file export, Tops merit functions, NotePad++ editor, a user selectable private folder, Q-Type Asphere improvement (Premium edition only) and an updated help system. This release also includes updated glass and vendor lens catalogues. The new Tops merit functions are based on merit functions developed in the 1960s and 1970s by professor Charles Wynne, Prudence Wormell, Dr Michael Kidger, David Freeman and others.

The Tops version will only work with the Standard and Premium editions of Oslo, but Tops_edu will work with Oslo Edu and Oslo Light. Both will generate an error function which can be used off the shelf for rapid improvement of many types of rotationally symmetric lenses, or tailored to finalise the design by adjustment of weights and targets.
