Nidek AR-330A Auto Refractor

(Pre-owned item 1 only at this time)

The combination of new measuring principle - Pupil Zone Imaging Method - and
unique technology - SLD - offers high accuracy and reliability in refraction
measurement.
The NIDEK AR-330A / 310A adopts the advanced Pupil Zone
Imaging Method for refraction measurement, which analyzes a
wider area (Max. ø4 mm) to obtain more reliable and realistic
data that is closer to subjective refraction.
Highly Accurate Refractometer
1. Pupil Zone Imaging Method
The AR-330A / 310A uses the SLD (Super Luminescent Diode) and
highly sensitive CCD device for improved image quality. The
image with the SLD is sharper and clearer than those with the
LED, and the system offers greatly improved measurement
capability even with dense cataract and IOL implanted eyes.

Clear image and data display with user-friendly guidance allow easier and
more reliable operation. Projected double mire rings on the cornea helps
better observation of the corneal shape and irregular astigmatism.
The clear 5.7-inch color LCD with
tilting function offers easy operation
even for a standing operator.

The auto-alignment (X & Y directions), auto-focusing (Z direction)
and auto-shooting provide faster, simpler and more accurate
measurements. When alignment is performed correctly,
measurement starts automatically.
