Auto Ref/Keratometer i-Optik ARK-910

Manufacturer: i-Optik (Ningbo Ming Sing Optical R&D), China

Description:
Combined auto refractometer/keratometer for objective measurement of refractive error and corneal curvature. 3D auto tracking and focus aligns to the eye automatically — the operator only positions the patient. LD light source and a high-sensitivity CCD deliver stable readings with pupils from 2.0 mm.

Application:
Objective refractometry and keratometry for spectacle and contact lens fitting; data transfer to a computerized vision tester via RS-232/Bluetooth.

Categories: ,
