ACCUREF K-900/R-800

ACCUREF K-900/R-800

In the pursuit of quality and ergonomics, the highest level of perfection and beauty has been achieved.

Auto Refract-Keratometer ACCUREF K-900

New Generation DESIGN & STYLE

Exquisite detail and quality.
Sophisticated shape combined with soft curves and the attractive color with high quality two-tone metallic and pearlescent paintwork which complements any interior and appeals atmosphere of trust to the customer.

Feather-touch sensor button

The feather-touch sensor button used to interface with the screen enables sensitive and accurate operation.

Newly designed optical unit with further improved accuracy

The newly designed optical unit allows measurement of the minimum pupil diameter up to 2.0 mm and high-accuracy measurement.
Useful function for actual measurement such as display of reliability warning indicator has been added.

Improved side flaps,head rest and chin rest

Side flaps mounted to each side of the measurement window enabling to block out the light realizes high accuracy. The modified shapes of the forehead rest and the chin rest help to minimize stress of the patient.

New Joystick

The completely redesigned joystick with the shape and top button allows the operator to control the unit with more precise and instinctive movement.

Newly designed IOL Mode [color focus indicator]

A subject with IOL was conventionally difficult to measure but this newly designed IOL mode has made it much easier.

Scotopic & Photopic Pupil Diameter Measurement

Both scotopic and photopic measurements are available.

Unique LCD Monitor

A swivel function to the left (30°) and a vertical tilt function (40°) have been added to the monitor unit. This swivel function allows measurement while supporting the patient.
