我们描述了 HAWK-I 的设计、开发和性能，HAWK-I 是 ESO 甚大望远镜的新型高灵敏度宽视场 K 波段成像仪，它配备了四个 2 k × 2 k 阵列的马赛克，工作范围为 0.9−2.4 μm，超过 7.5 × 7.5 �，像素为 0.1 ��。一个新颖的特点是使用全反射光学器件，再加上具有出色吞吐量的滤光片和高量子效率的探测器，产生了极高的吞吐量。调试和科学验证观测已经提供了各种优秀而深入的图像，证明了其在解决当前感兴趣的重要天体物理问题方面的巨大科学潜力。
We describe the design, development, and performance of HAWK-I, the new High-Acuity Wide-field K-band Imager for ESO’s Very Large Telescope, which is equipped with a mosaic of four 2 k × 2 k arrays and operates from 0.9−2.4 μm over 7.5 � × 7.5 � with 0.1 �� pixels. A novel feature is the use of all reflective optics that, together with filters of excellent throughput and detectors of high quantum efficiency, has yielded an extremely high throughput. Commissioning and science verification observations have already delivered a variety of excellent and deep images that demonstrate its high scientific potential for addressing important astrophysical questions of current interest.
