This revolutionary product will provide you with everything you need for any type of electroretinogram, visual evoked potential, or electro-oculogram. The ultra-bright ganzfeld – capable of over 15,000,000 different colors – will allow you to perform ERGs you never imagined possible including on-off, double flash, photopic negative response, scotopic threshold response, and s-cone ERGs. Amplification with our digital biomedical amplifiers allows faithful reproduction of every nuance of your recordings.
