MICRON® Ganzfeld ERG

Electrophysiology tool optimized for the unique retinal response of rodent photoreceptors

  • Specific capability to excite S-Cones, M-Cones and rods
  • Dark lab technology allows eye to be dark adapted to the fullest for murine rod
  • Software suite controls the stimulus for UV and green

Unique ERG tools specifically for rodents

The Phoenix CLEAN signal processing routine filters out 60 Hz noise often found in building power systems. The unique process avoids the distorting effects of notch filters or bandwidth clipping, and allows single ERG measurements without needing to average the low-level ERG signals to eliminate the noise.

Ganzfeld ERG

A stand-alone unit featuring compactness and a large dynamic range. Both UV and green light available to match the rods of the rodent eye.

Focal ERG

Attached to the MICRON® imaging system and allows precise targeting of the retinal location to be studied while maintaining dark adaptation. Supports a wide range of focal spots available.

A fully functional system

Equipped with a full range of functions such as flicker, background saturation and OP wave extraction.

Equipped with CLEAN, a Phoenix innovation that identically removes 60 Hz pickup.

Ganzfeld ERG for rodents

The Phoenix MICRON® Ganzfeld ERG System is optimized for the unique retinal response of rodent photoreceptors and provides the specific capability to excite SCones, MCones, and rods. The system is equipped with the unique Phoenix “dark lab” technology so that the eye can be dark adapted to the fullest for murine rods. A proprietary software suite controls the stimulus for UV and green—providing full
control of pulse width, delay, intensity, and flicker.

The unique Maxwellian view design enables placing the corneal electrode on the front lens. With an infrared camera for guidance, the electrode can be gently contacted to the cornea even in the dark, keeping absolutely dark adaptation and stable contact to the eye.
