Marco Nidek - ARk-900
by Marco Nidek


The ARK-900 incorporates many impressive features such as Marco’s exclusive Advanced Refraction Logic, Averaged multiple readings, Automatic binocular P.D. measurement, and calculation for near PD., as well as a mode for monocular P.D. and corneal diameter measurements. An electronic joystick elevation controls makes alignment and focusing a simple and fast one-handed operation. The instrument can be used separately as an auto refractor, keratometer, or of course, both simultaneously. All functions are conveniently displayed on a high resolution TV monitor and the patient data appears on a single printout.
