Product Performance:
Electronic Keratometer is made of three parts, including light source, Measurement of optical system and display system. To focus, the operator need make the unit up and down, , back and forth. When the focusing condition is met, When all the four image points are in the center of the screen, instrument will calculate automatically the curvature radius and diopter and display the result on the screen.
Technical Data
Measuring range：6.5mm～9.5mm curvature radius
Center measuring area of Corneal Radius: Φ3mm～Φ4mm;
Digital Display Resolution of curvature radius: 0.01mm;
Precision of curvature radius of cornea: ±0.05mm;
Axial resolution of the main meridian: 1°;
Radial deviation of the measurement of the main meridian
a）curvature radius deviation of the main meridian≤0.3mm, measurement of main meridian axial deviation: ±4°;
b）curvature radius deviation of the main meridian＞0.3mm，measurement of main meridian axial deviation: ±2°;
Output: Wireless infrared thermal printer;
Voltage: DC4.5V（three AA battery）;
Rated input power: 500mW+15％;
Weight: <0.5kg;
Dimension: 240mm×90mm×60mm.
