    • An emulator including a beam splitter for splitting incoming light energy into a first component directed along a first optical path, and a second component directed along a second optical path distinct from the first optical path. The emulator includes a first receptacle positioned to pass light energy directed along only the first optical path. The first receptacle is capable of receiving an add lens for providing an add power. A beam combiner is positioned to combine light energy of the second component with light energy of the first component that has passed the first receptacle, i.e. to have the add power applied, and to direct the combined light energy along a common optical path. Additional receptacles are provided that are capable of receiving a sphere and/or a cylindrical lens in position to pass the combined light energy traveling along the common optical path.
    • 一种仿真器,包括用于将入射光能分解成沿着第一光路指向的第一分量的分束器,以及沿着与第一光路不同的第二光路指向的第二分量。 仿真器包括第一插座,其被定位成传递仅沿着第一光路指向的光能。 第一容器能够接收用于提供附加功率的附加镜头。 光束组合器被定位成将第二部件的光能与已经通过第一插座的第一部件的光能组合,即具有施加的附加功率,并沿着公共光路引导组合的光能。 提供了附加的插座,其能够接收球体和/或柱面透镜在适当位置以通过沿着公共光路行进的组合光能量。
