Available with Integrated Through-Pupil Illumination (TPI) for Improved Infrared
Fundus Monitoring |
| The FMS IV integrated fixation
monitoring, refractor, and stimulus display system provides the ultimate
control of fixation, alignment, focus, and high-resolution, high-intensity
stimulus delivery for multifocal visual electrophysiological testing.
Designed and constructed only by Electro-Diagnostic Imaging, Inc.,
the FMS IV is fully integrated with, and completely controlled by
your VERIS™ system software. |

- Green: 530 nm typical, half-width 30 nm at 25 deg. C.
- Blue: 470 nm typical, half-width 20 nm at 25 deg. C.
- Greater than 300 cd/m2 maximum luminance
- Field of stimulation: approx. 50 deg. diameter
- Infrared Video Eye and Fundus Imaging
- IR Eye camera provides magnified image of eye for accurate alignment and monitoring.
- IR fundus camera provides fundus image for accurate stimulus positioning and fixation monitoring during testing.
- Integrated software allows toggling between external eye and fundus views.
- Both use IR LEDs: 850 nm dominant wavelength; half-width 45 nm at half intensity.
- Through-Pupil Illumination (TPI)
- Eliminates the need for special IR electrodes or other devices to provide infrared fundus illumination and provides improved fundus image quality.
- Refractor provides single-knob correction of spherical refractive error with automatic compensation for magnification to project properly focused and sized stimulus to the subject's retina.
- Maximum myopic correction > -20 D SPH
