Product Highlights

Key Features

  • Joystick alignment with automatic capture
  • One Instrument, Four Measurement Modes — R&K / REF / KRT / CLBC
  • 5.7-inch TFT color LCD
  • Direct access through physical buttons
  • Built-in thermal printer
Clinical Use

Applications

Objective refraction and corneal curvature measurement in optical practices, optometry clinics and eye-care departments. Examination results require professional interpretation.

One Instrument, Four Measurement Modes

Select the measurement mode from the control panel to suit the examination sequence.

R&K

Combined measurement

Refraction and keratometry in a combined measurement mode.

REF

Refraction

Objective refractive measurement with sphere, cylinder and axis output.

KRT

Keratometry

Corneal curvature, corneal power and corneal astigmatism.

CLBC

Contact lens base curve

A dedicated mode for measuring contact lens base curvature.

Familiar Controls, a Straightforward Sequence

ARK-8900 — Joystick alignment with automatic capture

Joystick alignment with automatic capture

Fine-position the instrument with the joystick while checking the alignment target on the color display. Automatic measurement starts when the alignment and focus conditions are met; manual measurement is also available.

ARK-8900 — Direct access through physical buttons

Direct access through physical buttons

Use the control panel to select measurement modes, review results and adjust measurement and print settings. Automatic fogging supports the refraction measurement sequence.

ARK-8900 — Results on paper, at the instrument

Results on paper, at the instrument

The integrated thermal printer provides a local printout. Select the print format and included data fields, with automatic printing after both eyes available in the instrument settings.

ARK-8900 Frequently Asked Questions

Is the ARK-8900 fully automatic?

The operator aligns and focuses the instrument with the joystick. Automatic capture is available once measurement conditions are met. It is not a fully automatic three-axis positioning system.

What does CLBC mode measure?

CLBC is the contact lens base-curve measurement mode. It does not refer to axial length measurement or full corneal topography.

Can the measurement results be printed?

Yes. The instrument includes a thermal printer with selectable print formats and configurable data fields.
