Auto Refractometer Optical Instruments Optometrist Autorefractor with Keratometer Comprehensive Optometry with Thermal Printing 61bk

Refraction Metrics: It measures vertex distances at 0mm, 12mm, 13.75mm. Spherical values range from -20 to +20D (at VD=12), with a step of 0.12/0.25m - 1. Cylinder values span -8 to +8m - 1, also with a 0.12/0.25m - 1 step, and axis from 0 - 180° in 1° increments. Pupil distance can be measured from 45 - 88mm in 1mm steps, and it can handle a minimum pupil size of 2.0mm.Keratometry Metrics: The auto refractometer measures corneal radius of curvature from 5.0 - 10mm (in 0.01mm increments), corneal power from 33.7 - 67.50D (assuming an equivalent refractive index of 1.337), with an increment selectable from 0.12, 0.25m - 1. It also measures corneal astigmatism from 0.00 - 8.00m - 1 (increments selectable from 0.12, 0.25m - 1), axis from 1 - 180° (1° increment), and corneal diameter from 2.0 - 14mm (0.1mm increment).
