A Highly Accurate, Precise, and Versatile Eye Tracker
The EyeLink 1000 Plus is the world’s most precise and accurate video-based eye tracker, sampling binocularly at up to 2000 Hz. It is highly customizable, with multiple mount options, interchangeable lenses, and head-fixed and head-free tracking modes. This versatility facilitates eye-tracking across a wide range of experimental setups and participant groups, from infants to the elderly and non-human species too. It also enables integration with EEG, fMRI, MEG, ECoG, and other devices.

A Flexible and Modular Eye-Tracking Solution
At the heart of the EyeLink 1000 Plus is our unique high-speed camera, capable of recording binocular eye movements at up to 2000 frames per second. The camera images are processed by software running on a dedicated Host PC, using a real-time operating system to ensure outstanding temporal precision. Choose either a desktop Host PC – perfect for standard laboratory settings, or a laptop Host PC for a smaller footprint and increased flexibility. Gaze data are returned from the Host PC to the stimulus presentation computer and other external devices via an Ethernet link and/or analog voltage, with an end-to-end delay of less than 3 ms – perfect for gaze-contingent tasks.
Our camera can be transferred between multiple mounts, allowing for a truly flexible eye-tracking solution that can meet a wide range of research needs:
The Desktop Mount sits below the tracked area and is perfect for traditional screen-based eye tracking. It allows the camera to operate at a range of 40-70cm, so no electronics need to be near the participant’s head, making it perfect for research involving EEG or TMS. It supports both the Head-Stabilized and Remote head free-to-move modes and is the ideal choice for most standard screen-based eye-tracking scenarios.
The Tower Mount is perfect for tracking gaze while participants interact with touchscreens or for research that requires eye movements to be tracked over large degrees of visual angle. The EyeLink camera views the eye from above via an infrared hot mirror, leaving the space in front of the subject unoccupied and extending the binocular trackable range to 60 degrees horizontally and 40 degrees vertically. Contact us to learn about customized Tower Mount solutions for writing/drawing research.
The LCD Arm Mount is perfect for working with infants, toddlers, and patients, as well as participants in difficult-to-record positions. The easily-positioned hydraulic arm holds an LCD monitor (with speakers) as well as the EyeLink camera and illuminator. The entire eye-tracking apparatus and display can be easily moved into place in front of the participant. The LCD Arm Mount also supports both Head-Stabilized and Remote head free-to-move modes.
The Long Range Mount and associated fiber-optic camera upgrade components are designed for eye-tracking scenarios that require the camera to be up to 150 cm from the eye. For further details see our fMRI and MEG Systems page.
For NHP tracking, the Primate Mount holds the camera and infrared illuminator in a compact, out-of-the-way bracket. An infrared-reflecting hot mirror approach accommodates a wide range of viewing setups and wide visual angles within very small space requirements. The Desktop Mount can also be used in NHP settings for mirrorless operation.
Accessories / Upgrades
There are a number of accessories that you can add to the EyeLink 1000 Plus. If you would like further details, please contact our sales team at sales@sr-research.com, and they will be happy to answer any questions.
The SR Research Head Support is an extremely sturdy, high-quality chin and forehead rest, suitable for use in any behavioral research laboratory. Both the chin and forehead supports can be adjusted in height independently, and the chin support can also be adjusted in depth for extra comfort and better head positioning. You can use just the chin rest (e.g., for EEG experiments in which you want to avoid putting pressure on the frontal electrodes) or just the forehead rest (e.g., for tasks involving speech production). The SR Research Head Support is made using a small-batch process by our expert engineers – see our timelapse video.
The Remote camera upgrade allows head free eye tracking, and is useful for situations in which head stabilization is not desirable, but high accuracy and resolution are still required – such as for research involving EEG, TMS, or when working with infants, children, and special populations. It has consistent binocular/monocular tracking at up to 1000 Hz with an average accuracy of ~0.5 degrees. It is compatible with Desktop and Arm Mounts and a choice of lenses allows a range of headbox sizes.
The Analog Output card is intended for research settings in which digital gaze data cannot be accessed over the ethernet link. It provides analog output of X and Y position data and pupil size. Data is updated every sample (up to 2000 Hz). The programmable range is between +/- 10 volts. It has an analog breakout board with BNC connectors.
We can provide high-performance stimulus presentation and response hardware. We carefully measure audio and visual stimulus delivery times and can provide highly optimized preconfigured Display PCs with known timing properties. We provide fast LCD Displays (up to 240Hz) that have been timing-tested and confirmed to have accurate vertical refresh capabilities – perfect for gaze-contingent research. We also supply millisecond accurate response devices, with a range of button layouts.
