Sophisticated Software Allows Complex Optical Design
Software has pushed the optics and photonics fields forward in myriad ways, sometimes with profound effects on business and culture. Would we have been able to take full advantage of the many technology advances in the past five decades – including the laser – if it weren’t for optical design software? Optical design software often is indispensable to daily life for those working with optical systems in lasers, imaging, nonimaging optics or visual systems. From lithograp...
