Description
Autorefkeratometer HRK-7000
The unique HRK-7000 Autorefractometer combines the quality and reliability of its predecessor, the MRK-3100, with the latest technology to deliver exceptionally accurate keratometry and refractometry data.
The principle of operation of the HRK-7000 autorefkeratometer is based on the use of a special Hartmann-Shack wavefront sensor, which allows point-by-point analysis of the wavefront reflected from the retina of light. With the help of wavefront analysis, we can analyze the aberrations of the optical system of the eye and select the optimal correction.
SLD & High Sensitivity CCD
The new HRK-7000 Auto Refkeratometer delivers clear images using SLD (Super Luminescent Diode) and high sensitivity CCD.
Noise suppression technology ensures accurate results for ametropia, cataract or IOL.
Peripheral measurements The
HRK-7000 provides measurements of peripheral keratometry data, which can be very useful when fitting contact lenses.
6.5 Color LCD Display The TFT LCD color display guarantees clear real-time images.
Graphic display of the wave front map
The graphical display of refractive errors allows a better understanding of the condition of the patient’s eyes and the reliability of the assessment.
Accurate keratometry data
Reliable keratometry data thanks to the use of two mirror rings and two LEDs.
Easy setup
A convenient and intuitive interface allows the user to easily set the desired function and change settings without leaving the current page.
Convenient locking
You can lock the device with a single push of a button
Retro Illumination Mode
When using this mode, you can see defects in the lens or damage to the cornea, which helps you determine how healthy the patient’s eye is. When the patient is refractive, you can check the sphere, cylinder and axis, which is not possible with the normal examination mode
Work in the refraction system HRS-3100
Huvitz HRK-700 works great as part of the HRS-3100 optometric system (workstation, character projector, digital phoroptor, lensmeter). In addition, the device can work with an external monitor for a more visual display of measurement results.
