The misadjusting parameter of the misadjusted telescopic system is used to adjust the focusing posit ion of outgoing beam.
用失调望远系统的失调量变化调节出射光束聚焦点的位置，并对聚焦点的变化范围和光斑大小进行描述。
Because the beam formed by a tapered coupler is produced by many rays that emerge at slightly different angles, the outgoing beam is characterized by a relatively large divergence.
因为尖劈耦合器形成的光束是由许多出射角稍有不同的光线组成的，放出射光束的特点是具有较大的发散度。
