Tomey RT-7000 Autorefractor/Keratometer/Topographer

RefractometryKeratometorySPECIFICATIONS‐Dual CCD technology for RefractometryTwo CCD cameras are used to capture images for observation and forMeasurement while providing highly accurate measurement data.‐New Indices for KeratometryThe Corneal Irregular astigmatism display function is installed to expand the possibilityof Keratometer. This is the new function to measure the level of corneal irregularastigmatism which was difficult in the past.Measurment RangesRefraction MeasuremntSphere‐25.00D to ±22.00DIVD=12.0mmCylinder0D to ± 10.00DIVD=12.0mmAxis 0 to 180Corneal Curvature Measurement5.00mm to 11.00mmMeasurement Zone 3mm R:8.00mmCorneal MappingDisplay Range9 to 100 D‐Normal Mode1.0 to 8.0mm (R:8.00mm)‐Special Mode0.9 to 7.0 mm (R:8.00mm)Measurement TimeREFKRTMinimum Pupil Diameter0.2 Seconds0.1 Seconds2.2mmMinimum Measurment StepRefraction MeasurementSphere 0.01D
