diagnosing of blinding diseases.

A malfunction in the supply of oxygen can lead to a variety of retinal diseases. Enabling doctors to measure the oxygen level in the retinal blood vessels with a mobile tool will have a positive effect on disease prevention. With a long history in design and engineering in fundus camera system for OEM customers, Demcon focal has succeeded in this development which we called the Corimapper.

Within Demcon focal, we developed the Corimapper handheld oximetry imager for early treatment of blinding diseases in premature babies. The solution includes compact optimum fundus design that avoids glares and has a multi-wavelength xenon illumination source, two cameras for the relevant wavelengths and a ring illumination. We designed and made a prototype that was accepted by the Dutch medical ethical committee and is currently used in clinical trials. For instance see the article below.

"demcon focal at its best"

The retina imager in itself is already a highly complex optical design. Let alone that there is also a sensitive spectrometry challenge added to the job, including the processing to analyze the acquired data. The sweet spot for Demcon focal.
