CODE V 10.2, the newest release of the premier optical design software from Optical Research Associates (ORA), delivers a number of enhancements that simplify its use and provide greater flexibility for users. For example, CODE V 10.2 introduces improved ray tracing algorithms that increase robustness when designing optical systems with extreme aspheres, hyper-hemispherical fields of view (fisheye lenses), and highly tilted components. Most importantly, these new algorithms maintain the fast ray tracing speeds for which CODE V is well known. Plus, custom macro writing is simplified in CODE V 10.2, which now empowers users to specify any appropriate external program as the default text editor.
