CODE V 10.2 optical design software from Optical Research Associates has enhancements that simplify use and provide greater flexibility. Improved ray tracing algorithms accommodate design of optical systems with extreme aspheres, hyperhemispherical fields of view and highly tilted components. Custom macro writing has been simplified, enabling users to specify any appropriate external program as the default text editor. Expanded graphical output options include smarter defaults for producing optical system drawings with the View Lens feature. File conversion improvements allow all plots to be saved in common formats, including bmp, gif, jpeg, png and tiff. The updated status bar shows more user-selected system parameters, and the Transmission Analysis feature has been expanded to list Fresnel losses, absorption, diffraction efficiency and filter interferograms.
