Read full product description



The Topcon NW400 is equipped with automatic focusing and capture and a fully automated mechanism that moves the optical head from one eye to the other without operator intervention.

The large 10″ color touch-screen monitor allows for total control of the functions as well as displays the acquired images. A high resolution color sensor provides quality images with a 45° field of view. The TRC-NW400 has 9 internal fixation targets that facilitate the composition of wide angle views of the retina. The TRC-NW400 can be used as a stand-alone unit saving images to a USB drive, as well as sending the images to be saved to a remote server or EMR system. It is DICOM compliant and can be used without a computer, retrieving the modality work list with patient information directly from the EMR server. 

With the use of the optional IMAGEnet® 5 software, the TRC-NW400 can save and store the images to a local computer making them available for review.
