Product Information (  2019 - Auto Refractometer  | SBJ  | 20863 ) 

Accurate Refraction Measurement: The AR-1A provides precise measurements of sphere, cylinder, and axis, enabling reliable and consistent results. Large Pupil Zone Imaging Method: This method allows measurement of refraction over a wider area, up to 6 mm in diameter, and can indicate the difference between central and peripheral refraction. Super Luminescent Diode (SLD) and Highly Sensitive CCD Technology: The AR-1A uses an SLD for sharper and clearer images, even in dense cataractous eyes, combined with a highly sensitive CCD to detect even weak reflections. Y-direction Auto Tracking: The vertical auto-tracking system and auto-shot function ensure fast and accurate measurements with minimal manual intervention. Retro-illumination: Retro-illumination enables observation of opacity in the optical media of the eye. Accommodation Measurement: The AR-1A can measure accommodation amplitude. User-Friendly Design: Features like a tiltable color LCD screen, high
