SR Research produces the EyeLink family of high-speed, video-based eye tracking equipment and has been enabling scientists to perform cutting edge eye tracking research since the early 1990s. EyeLink systems are renowned for their outstanding technical specifications, temporal precision and superb accuracy. The EyeLink 1000 Plus has the world's lowest spatial noise and can be used in the laboratory, with or without head stabilization, or in sensitive environments like MEG/MRI. Our new EyeLink Portable Duo offers the same high levels of data quality and dual modes of use in a small, portable package that is exceptionally easy to use both in and out of the lab. In addition to our exceptional hardware, SR Research also provides sophisticated experiment delivery and analysis software, and a truly legendary support service.
