title: [Optical properties and clinical performance of the Topcon retinal camera TRC-FET 3 (author's transl)].
abstract: A Topcon Retinal Camera TRC-FET 3 was tested for several weeks under laboratory and clinical routine conditions. The optical properties turned out as good and meet the requirements for retinal cameras in all details. Remarkable is the high speed of the imaging system, which allows working with low flash energies and with high flash frequency. The resolving power is high (8 microns at the center) and decreases slowly to the periphery. The illumination of the fundus is fairly homogeneous. Many filters of good performance are provided. There was no problem in handling the camera, and the test photographs as well as the clinical routine photographs were of high quality.
