本文报道了利用哈勃空间望远镜上的NICMOS在引力透镜系统B1938 + 666中发现的一个弧秒直径的爱因斯坦环。透镜星系也被探测到，并且很可能是一个早期类型的星系。环的建模，并比较从MERLIN地图的无线电结构。我们表明，爱因斯坦环是一致的引力透镜的扩展红外组件，中心之间的两个无线电组件。
We report the discovery, using NICMOS on the Hubble Space Telescope, of an arcsec-diameter Einstein ring in the gravitational lens system B1938 + 666. The lensing galaxy is also detected, and is most likely an early-type galaxy. Modelling of the ring is presented and compared with the radio structure from MERLIN maps. We show that the Einstein ring is consistent with the gravitational lensing of an extended infrared component, centred between the two radio components.
