The Voyager 2 photopolarimeter successfully completed the Uranus encounter, acquiring new data on the planet's atmosphere, its principal satellites, and its ring system. Spatially resolved photometry of the atmosphere at 0.27 micrometer shows no enhancement in absorption toward the pole, unlike the case for Jupiter and Saturn. Stellar occultation measurements indicate the temperature at the 1-millibar level over the north pole is near 90 kelvins. The geometric albedos of the five large satellites of Uranus were measured at 0.27 and 0.75 micrometer and indicate the presence of low albedo, spetrally flat absorbing material. Titania seems to have a fluffy surface, as indicated by its phase curve. The nine ground-based rings were detected, and their internal structure, optical depths, and positions were determined. The sharp edges of the in ring made it possible to measure its edge thickness (less than 150 meters) and particle sizes (less than 30 meters); little or no dust was detcted. New narrow rings and partial rings (arcs) were measured, and the narrow component of the eta ring was found to be discontinuous.
航海者 2 号光偏振计成功完成了天王星探测任务，获取了有关该行星大气、主要卫星及其环系的新数据。对 0.27 微米处大气的空间分辨光度测量显示，与木星和土星不同，其极地没有吸收增强现象。恒星掩星测量表明，北极 1 毫巴高度的温度接近 90 开尔文。对天王星的五颗大卫星的几何反照率在 0.27 和 0.75 微米处进行了测量，表明存在低反照率、光谱平坦的吸收物质。泰坦似乎有一个蓬松的表面，这表明它的相位曲线。九个地基环被探测到，并确定了它们的内部结构、光学深度和位置。由于内环的锐利边缘，可以测量其边缘厚度（小于 150 米）和颗粒大小（小于 30 米）；几乎没有或没有检测到尘埃。新的窄环和部分环（弧）被测量，发现 eta 环的窄部分是不连续的。
