![]() Other optical systems such as prisms and faceted reflectors cannot be described by using sequential ray-tracing. ![]() As camera lenses and microscopes can be developed in terms of a sequential list of surfaces, rays can be traced sequentially from the object surface to each surface in a specific sequential order using sequential ray-tracing. Designers using such packages also may find themselves limited if they need to export their designs to other computer-aided design (CAD) packages for further optomechanical analysis or three-dimensional (3-D) rendering.ĭesigners must also determine whether they require sequential or nonsequential ray-tracing or a combination of both. ![]() Low-cost packages, which can be effective for several tasks, such as examining the structure of optics designs, may be limited in the number of off-the-shelf components available for designer selection. However, in choosing a specific package for optical design, developers must carefully consider the performance and cost goals. ![]() Of the numerous optical-design and analysis packages available, most operate on Windows-based PCs. 36), developers can experiment with different optics and combinations of lenses and optomechanical systems and build prototype models that can graphically show the completed design of a lens, optical, or optomechanical system. With more than 20 optical-design and optical-system design and simulation packages available (see table on p. Designers of optical systems can, to some extent, abandon the optical benches of the past in favor of PC-based optical-design software.
