Reproducible Measurement Results

Testing has shown that the NeurOptics Pupillometer is consistent from unit to unit and operator to operator. In fact, the NeurOptics Pupillometer has the highest accuracy and lowest error of all commercially available pupillometers, while at the same time being the most economical hand-held infrared device.


Adjustable settings (light stimulus intensity and duration, duration and onset of measurement, background illumination)

Data stored on device, results uploadable to external computer via Bluetooth®

Video playback wand downloading video of last measurement

Video of the measurement can be played on the device’s screen

Continuous pupil recording (≤ 10 minutes without light stimulus, ≤ 41 seconds with light stimulus)
