Espion Profile Ganzfeld The Espion Profile Ganzfeld ERG system uses software and hardware developed entirely by Diagnosys LLC to provide a compact, transportable system for recording not only any ISCEV standard ERG, but any conceivable ERG, EOG, or flash VEP test. Based on the world’s most advanced Ganzfeld stimulator, the ColorDome, paired with the most advanced electrophysiology amplifiers available, the precision-machined cart-mounted system is a powerful addition to any clinic or research facility. The ColorDome’s monocular companion, the ColorBurst, is optimized for pediatric or research use and may be mounted on the cart in addition to or in place of the ColorDome. Stimulus features ColorDome* • Flash luminance range from • Flash luminance range from 10-9 to 40 cd.s/m2 10-9 to 3000cd.s/m2 • Anywhere within this > 10 billion • Anywhere within this > trillion to to one range luminance can be changed one range luminance can be changed with no less than 1% resolution with no less than 1% resolution • Any color background from • Any color background from 10-9 to 500 cd/m2 10-9 to 500 cd/m2 • Easily supports any ISCEV • Supports any Ganzfeld ERG standard or ancillary ERG test test ever devised *see brochures for more detailed specs Hardware features • 5 Channel headbox with industry-first 32-bit amplifiers • Drives either or both ColorDome and ColorBurst Stimulators • Integrated Power Supply Isolation Unit • 3 system configurations: Stand-alone, cart-mounted with power lift table (shown right) Stand-alone, bench-mounted (overleaf) or integrated into the Espion System
