Nidek RT900 Auto Phoropter Head

The Nidek Refractor model RT-900 is a computerized refractor used for subjective refraction when connected to the Nidek Auto Refractometer (AR), Auto Ref/ Keratometer (ARK) and Auto Lensmeter (LM)*. The operator has a fully integrated refraction system that simplifies and speeds up refraction.
The RT-900 includes a refractor head, a remote control, a relay box, and a printer (option).

The relay box serves as a link to the refractor head, remote control and printer, and also functions as a communication link to the AR and/or LM.

The refractor head provides a display for viewing measurements. The remote control allows the operator to perform most operations from the integrated console by linking the refractor and the connected chart presenting device.
