The University of Rochester will build a third generation near infrared camera. The new 256x256 InSb camera will be sensitive from 1 - 5 micron, and will be capable of spatial resolutions of 0.1 arcsec/pixel on large telescopes. Filters will include standard broadband filters, and a circular variable filter wheel, providing approximately 1% spectral resolution. The photometer will be built on an optical bench, which will later accommodate a Fabry-Perot interferometer. A flexible, computer programmable array controller for this array and other arrays that will become available in the future has been designed and tested. As well, the dewar that houses the array can easily accommodate different format and/or material detector arrays. Infrared arrays are available for NASA sponsored experiments. This camera will efficiently obtain large scale images at large telescopes with excellent sensitivity, spatial resolution and spectral resolution. As with previous generation cameras, other astronomers will collaborate with Rochester group and they are willing to provide others with technical information on the camera components. Astronomical observations of star formation regions, regions associated with late stellar evolution, active and starburst galazies, gravitational lens galaxies, brown dwarfs and the galatic center are planned.

罗切斯特大学将建造第三代近红外相机。 新型 256x256 InSb 相机将对 1 - 5 微米敏感，并且在大型望远镜上能够实现 0.1 角秒/像素的空间分辨率。 滤光片将包括标准宽带滤光片和圆形可变滤光片轮，提供大约 1% 的光谱分辨率。 光度计将建立在光学平台上，随后将容纳法布里-珀罗干涉仪。 用于该阵列和将来可用的其他阵列的灵活的计算机可编程阵列控制器已经设计和测试。 此外，容纳阵列的杜瓦瓶可以轻松容纳不同格式和/或材料的探测器阵列。 红外阵列可用于 NASA 赞助的实验。 该相机将在大型望远镜上有效地获取大尺度图像，具有出色的灵敏度、空间分辨率和光谱分辨率。 与上一代相机一样，其他天文学家将与罗切斯特小组合作，他们愿意向其他人提供有关相机组件的技术信息。 计划对恒星形成区域、与恒星演化晚期有关的区域、活动星系和星暴星系、引力透镜星系、褐矮星和星系中心进行天文观测。
