INTRODUCTION
Thank you for purchasing the TOPCON TRC-NW8F, TRC-NW8F plus NON-MYDRIATIC RETINAL
CAMERA.
This instrument is used to observe and photograph the fundus of the eye.
There are two versions of this device; the TRC-NW8F is not equipped with Fundus Autofluorescence photogra-
phy (FAF photography) while the TRC-NW8F plus*1 is equipped with FAF photography functionality.
This instrument has the following features:
• The TRC-NW8F and TRC-NW8F plus perform fluorescein photography (FA photography) simply by changing
the photography mode.
• With the TRC-NW8F plus Fundus Autofluorescence observation can be performed on the built-in color LCD
monitor.
• Photographs can be taken through pupils 4.0mm or larger. (3.3mm or larger if small pupil diaphragm is on)
• Auto focus function
• Red-free photography with red-free filter*2 (Only in TRC-NW8F)
*1: "plus" is the catalog symbol.
*2: Hereinafter, RF filter
This manual outlines the TRC-NW8F/TRC-NW8F plus NON-MYDRIATIC RETINAL CAMERA, including oper-
ating procedures, troubleshooting, maintenance and cleaning.
