Description

Model:RET-C

Main functions
GIMAmp – DC Amplifier for Visual Electrophysiology

24bit high resolution A/D, higher than competitor’s 12/14 bit;
Optical isolated USB connection, powered by li-ion battery, totally isolated from AC power system, provide excellent anti-interference performance;
Automatically switched to USB power, when low battery;
Real time full digital filter, cut frequency & order for band bass, low pass, band stop, high pass, and comb filter can be independently set for each channel through software; Provide flexibility for your clinical handing and scientific research than ever;

2 channels by default, optional: 5 / 8 channels.

LightBurst® – Flash Stimulator

Small size, big energy;
Less than 3 Kg, test seated patient by default; Stimulator can also be taken down to test lying patient or infants; Test for dog, monkey, pig, mouse, rat, rabbit is also been supported conveniently;
18 groups of background, stimuli light source: white, red, blue, green and yellow; Optional: infra-red and ultra-violet for research purpose;
Small size leads to more efficient use of light energy, able to provide 100 cd·s/m2 white broad band stimuli in < 4ms, 10X ISCEV standard;

LCD Pattern Stimulator

CASE EXAMPLE 
VEP – depend on functional integrity of central vision at any level of the visual pathway including the eye, retina, the optic nerve, optic radiations, and occipital cortex;
ERG/FERG – mainly reflect function of rod/cone and connected bipolar cells, rod/cone system can be isolated through dark/light adaptation;
PERG – represent function of ganglion cells when photo-receptor & bipolar cells works fine;
EOG – is an electrophysiological test of function of the outer retina and retinal pigment epithelium (RPE).
Best configurability: checkerboard, horizontal/vertical stripes, rectangle stimuli; Reversal, on/off stimuli;
Fixation target and stimuli field can be adjusted;
Low-vision fixation target is available;

Hexagon & dartboard not available for RetiMINER-C.
