MODEL: RK-11  


Auto Refractor / Keratometer RK11


Viewlight- Autorefractor Keratometer Smart RK-11 is the new generation of ophthalmic equipment featuring an illumination sensor, focusing navigator, multilevel dial types, extremely rapid automatic measurements

and highly accurate data.

Illumination Sensor

RK11 features an Illumination sensor which automatically detects the brightness of the room and compensates the measurement results in order to provide adequate results. RK11 has a Ophthalmic system to reflect light from the retina and passing it through the cornea. This measurement is separated by using the filter and prism for accurate data.

Ergonomic Design

RK11 not only perform Refractometry and Keratometry, but also performs peripheral Keratometry and corneal size measuring.

Provides user-friendly environment by adopting smooth curved shape, stylish color, user-centered design and user interface.

Wide Range of Measurements

The RK11 offer the latest technology with wide range measurements including an ergonomic gun-type joystick which provides an easy grip feeling, allows a fast measurement image shooting, automatic chinrest mechanisms, and multi level locking system.

  • Automatic Vertical Tracking of the Pupil

  • Effective Management of Measurement Data

  • Support Various Mode of Measurements

  • Iris / Pupil Measurement

  • Measurement of Corneal Periphery

  • Target Image Brightness Control

  • Illumination Sensor

  • Convenient PD Measurement

  • Automatic Chinrest with Adjusting Mechanism

  • Multi Levels Locking System

  • USB Thermal Printer

  • IOL Mode

Jog Dial Measurement

RK11 offers a built in bluetooth software for Android and iOS applications designed for users to control the chart and phoropter while all data test are sent effectively and efficiently.

Auto Save / Printer

All RK11 test result are transferred to it's built-in high-speed thermal printer, auto memory data saving and replaceable printing paper
