- Selectable and intuitive manual operation
Manual measurement using the large, durable 7.0-inch touch screen is also possible with the ARK-F/AR-F. Alignment is easily achieved by simply long-pressing a position on the screen and an icon. Clearly identifiable icons assure intuitive operation. Moreover, a newly designed hand-held control and tablet control software are available as options that increase operator freedom and productivity.
- Large pupil zone imaging method
The large pupil zone imaging method enables the measurement of wider area refraction up to 6 mm diameter and can indicate the difference between the wide area refraction and central area refraction of up to 3.5 mm diameter.
- Super luminescent diode and highly sensitive CCD
Incorporation of the super luminescent diode (SLD) provides a sharper and clearer image compared to a conventional LED. The highly sensitive CCD detects the ring image even if the fundus reflection is weak.
- Keratometry measurement with mire ring (available for the ARK‐F)
The mire ring is used to measure keratometry. It reduces eyelid artifacts.
