Huvitz HRK-8000A

(Auto Ref/Keratometer)

Precision & Accuracy!

Unlike many conventional diagnostic devices, the HRK-8000A Auto Refractor / Keratometer is based on Hartmann-Shack wavefront sensor, which analyzes many focal spots of a light wavefront. It has the ability to measure not just the basic refraction error of a customer, but to obtain a spatially resolved refraction map.



Optical System

Wavefront Technology measures the wavefront of light reflected from the retina and the refractive power with various sensors divided by sectors and analyzes them with
extreme precision.

High Order Aberration Map is on!

Besides the conventional data such as Spherical, Cylinder and Axis, the high order aberration data is displayed in
a graphical Zernike refraction map for better understanding of patient’s eyes and superior clinical decision making.

PSF & Image Simulation

Point Spread Function (PSF) and chart simulation of retinal display can make patients understood in a much better way of their clinical status of eyes and customized lens benefits.

Color View Mode

The Full Color CCD camera and white LED light source in the auto ref-keratometer enable you to see eyes and
contact lens fitting status which was.

Contact Lens Fitting Assistance Guide

The World’s First contact lens fitting function in an auto ref-keratometer enables you to see fluorescein liquid with blue illumination.
