E3 System, 110 Volt power supply, ColorDome with Xenon & desktop OR stand (includes long cable), with power supply, and chin rest, Desktop computer & Espion Software is a clinical and research visual electrophysiology system that functions by presenting a light stimulus to the eye, and then capturing displaying and storing the waveform of the electrical response from the retina (corneal electrode) or brain (occipital skin electrodes).Configuration: D315-1-1-CDXRL-NN-N-N-D
An ophthalmic device used to record the changes in electric potential on or near the surface of the cornea to a reference distal point on the body, following stimulation of the retina by light, i.e., flashes of white light. The electroretinograph (ERG) recorder is used with a primary electrode [typically gold (Au), platinum (Pt) or silver (Ag)] and a reference electrode located almost anywhere on the body, e.g., cheek or ear lobe, and an amplifier that boosts the bioelectrical potential. Some are compatible with a personal computer (PC) for waveform storage and analysis. It is used in the diagnosis of retinal degeneration, night blindness, and circulatory disturbances of the retina.
