PC-based Desktop Pupillometer


Binocular dual-camera system measures both eyes at once

Multi-chromatic (4 ultra-bright color light stimulus: white, green, blue and red)

Designed for a variety of animal models (and pupil sizes)

Video stream captured at 30Hz, 0.05mm pixel resolution

Stimulates direct, consensual, or both eyes simultaneously

Pupil variables: Latency, diameter at onset and peak of constriction, constriction and dilation velocity, 75% recovery time)

Light intensities defined in Lux or pure radiometric units (W/m2); can be adjusted over ~5 logunit range by increments of 0.1 log-units

Automatic tracking and pupil detection

Waveform of light stimulation can be customized using a simple graphical interface or defined in a file using Microsoft Excel®

Saves pupil profile and light stimulus data in a file (Excel® compatible) for external/ independent analysis
