CELERIS: Visual Electrophysiology Simplified

Celeris is rapidly becoming the preferred choice for rodent and small animal visual electrophysiology! Its sleek design makes for a high-throughput machine that is simple even for novices.

Exploded Celeris

Light Guide Electrodes

A dual function electrode-stimulator simultaneously delivers light stimulus while recording neural activity. How does it work? Our patented design wraps a conductive metal around a ‘light pipe’ that directly touches the eye.


Flash Stimulation

RGB color with optional UV

Sizes made for different animals

Luminance ranges dim to bright


Pattern Stimulation

Pattern ERG and VEP

Dual eye pattern stimulation

Multifocal ERG

Celeris Accessories
