This high-performance research system captures gaze data at speeds up to 1200 Hz. A screen-based eye tracker for extensive research from fixation-based studies to micro-saccades.
Tobii Pro Spectrum is our most advanced eye tracking platform, designed for extensive studies into human behavior and the mechanics of the fastest eye movements such as saccades, tremors, and micro-saccades. The system can capture data in high sampling frequency, while still allowing for natural head movement.
Tobii Pro Spectrum provides exceptional flexibility, accommodating a wide array of research scenarios and study designs. This system can be used with the provided screen or with just the eye tracker, enabling both on-screen and real-world stimuli, such as physical objects or people.
Multiple sampling rate options accommodate everything from fixation-based research to studies with more intense requirements on data granularity and time-based measurements.
The 8-bit TTL port and precise timing enable seamless synchronization capabilities with external biometric data sources such as EEG, GSR, or ECG, providing a holistic view of behavior.
Tobii Pro Spectrum tolerates larger and faster head movements than any other high-frequency screen-based eye tracker on the market. Tracking also resumes quickly if the subject moves in and out of the track box. With its ability to track freely moving subjects, Tobii Pro Spectrum greatly facilitates research with children.
Tobii Pro Spectrum is extremely accurate and precise with unparalleled tracking robustness, which makes it possible to study a very large portion of the population in many real-life conditions.
Tobii’s patented 3D eye model delivers high-caliber gaze data

Detects eyes instantly with minimal data loss during blinks or looking away
Allows precise synchronization of gaze information with other data sources
Captures pupil data at the same sampling rate as the gaze data
Provides eye images to understand what affects the data
Maintains tracking robustness in different lighting environments
In this study, Opwonya and colleagues (2022) examined executive control deficits and saccade behavioral changes in patients with MCI. For this, four saccadic eye-movement paradigms were used, including the prosaccade/antisaccade and the go/no-go paradigms. Eye movements were recorded using Tobii Pro Spectrum at 300Hz.
In this study, Ishikawa and colleagues (2022) combined heart rate (HR) and eye movement measures to determine whether the modulation of infant gaze following behavior based on social context is mediated by the infant’s HR. Eye movements were recorded with Tobii Pro Spectrum and allowed to identify trials with successful gaze following.
Mellor and Psouni (2021) measured differences in attentional vigilance toward emotional faces as a function of priming (neutral vs. secure) and attachment avoidance. Tobii Pro Spectrum was used to measure saccadic and microsaccadic eye movements. Reaction time and microsaccadic data strongly correlated, suggesting that they capture attention similarly.

Tobii Pro Spectrum's high data quality has been confirmed through extensive testing. We use well-documented test methods that span from systematic variations of the environmental conditions to a general assessment of the eye tracker performance with a large population of individuals.
Consistent reproducibility in studies is guaranteed with quality control procedures throughout the entire production process, including camera focus and the calibration of each unit. Multiple product certifications ensure that quality and user safety requirements are met.
The eye tracker comes fully assembled in the supplied travel case and doesn't require manual configuration with the setup of cameras, lenses, etc. Researchers can rely on quick, stable calibration of subjects and productively track the subjects they have attained for their study.
Software for the stand-alone configuration accommodates studies that involve real-world stimuli
VESA mounting available for fixed table or wall installation
Handle allows for smooth adjustment when accommodating subjects of different heights
The eye tracker unit can be used together with the provided monitor, or it can be used alone with other screens or real-world stimuli.
The removable high-resolution 24" monitor accommodates the display of on-screen stimuli. A low and stable response time of less than five milliseconds makes it suitable for studies where control of the timing of the stimuli presentation is essential. The IPS panel has a 178-degree viewing angle.
