SINFONI是一种自适应光学辅助近红外积分场光谱仪，目前正在位于智利帕拉纳尔的VLT单元望远镜4 （YEPUN）的Cassegrain焦点上进行安装和调试。焦平面仪器（SPIFFI）同时提供2048个连续空间像素的光谱，覆盖二维视场，空间填充系数几乎为100%，J， H和K波段的光谱分辨率为~3500。它是由自适应光学模块，一个60元双变形镜技术/曲率传感系统，源自澳门，升级到激光导星操作。本文报道了自适应光学模块的首光（2004年5月31日）。在第一次调试期间验证了自然导星模式下的性能，并为激光导星模式进行了准备测试。ao模块与SPIFFI的联合操作将在7月的第二次调试期间开始。SINFONI计划于2005年4月以自然导星模式提供给社区。在成功完成激光导星设备调试后，仪器将在2005年以激光导星模式进行调试。
SINFONI is an Adaptive Optics assisted near infrared Integral Field Spectrometer, currently in the process of installation and commissioning at the Cassegrain focus of VLT Unit Telescope 4 (YEPUN) in Paranal (Chile). The focal plane instrument (SPIFFI) provides simultaneous spectra of 2048 contiguous spatial pixels covering a two dimensional field of view with almost 100% spatial fill factor and with a spectral resolution of ~3500 in the J, H and K bands. It is fed by the Adaptive Optics Module, a 60 elements bimorph deformable mirror technology / curvature sensing system, derived from MACAO and upgraded to Laser Guide Star operations. This papers reports on the Adaptive Optics Module first light (May 31st 2004). Performances in Natural Guide Star mode were validated during the first commissioning and tests were carried out in preparation to the Laser Guide Star mode. Combined operations of the AO-Module with SPIFFI will start during the second commissioning in July. SINFONI is scheduled to be offered to the community in Natural Guide Star mode in April 2005. The commissioning of the instrument in Laser Guide Star mode will take place in the course of 2005 after successful completion of the Laser Guide Star Facility commissioning.
