DescriptionOptoelectronic stimulator, "ganzfeld" stimulations for flash VEP, flash ERG and sensory EOG. Pattern stimulations for ERG and VEP, multifocal stimulations for ERG and VEP, complies with international standards of electrophysiology."Ganzfeld" stimulations for flash VEP, flash ERG and sensory EOG. Complies with international standards of electrophysiology.
FeaturesStimuli for the study of parvo and magnocellular systems: luminance contrast gratings, color contrast gratings, flicker and patterns in motion. Includes near infra red video monitoring of eye fixation and electrodes. The visual tracking program records tracking eye movements while the patient is presented with a pattern in motion. The high input impedance and common mode rejection ratio insure unequalled performances. VEP obtained with a pattern reversal stimulusOptomechanic technology: uses halogen light sources coupled with interferential filters which insure a precise control of the luminance and the spectral characteristics of the stimulus. It uses a mechanical shutter providing a precise control of stimulus duration suitable for flash , on, off and flicker stimulations. All functions are motorized, allowing entirely automated examination protocols. The visual tracking program records tracking eye movements while the patient is presented with a pattern in motion. The high input impedance and common mode rejection ratio insure unequalled performances. VEP obtained with a pattern reversal stimulus
