The combination of new measuring principle - Pupil Zone Imaging Method - and unique technology - SLD - offers high accuracy and reliability in refraction measurement.

Pupil Zone Imaging Method
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.

SLD (Super Luminescent Diode)
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.
