Product description:
The INS-11010 provides highly accurate readings over a wide range. Used in measurements of Myopia, Astigmatism, Hyperopia, Presbyopia, Hrterophoria, Range of Accommodation, Convergence, Aniseiconia, Stereopsis and Binocular Vision. <br /><br />Rapid, accurate readings on binocular visual balance. <br />Speedy astigmatism tests with interlocking mechanism of the cross cylinder lens axis and the cylinder lens axis control ring. One touch accurate astigmatism readings are now possible.<br />In short, middle and long distance test, it is possible to have the optical axis of the lens and the line of patient vision coincide.<br /><br />Specifications:<br />Phoroptor OPTI+ Eco <br />Dimensions: 22 x 16 x 9 in / 56 x 41 x 23 cm <br />Weight: 15 lb / 7 kg <br /><br />Parameter:<br />Sphere power range:+16.75d~-19.00d,with minimum reading 0.25D or 0.12D(when +0.12D auxiliary lens or optional ±0.12D lens in use)+26.75D~-29.00S(when optional ±10.00D lens in use)<br /><br />Cylinder power range:0~-6.00D,with minimum reading 0.25D or 0.12D(when +0.12D auxiliary cylinder lens in use) 0~-8.00D(when -2.00 auxiliary cylinder lens in use)<br /><br />Cylinder axis:0-180°,5°steps<br />Cross cylinder:±0.25D reversal,±0.50D optional<br />Rotary prism:0?~20?,1? step<br />PD adjustment:48mm~80mm,1mm step<br />Forehead rest adjustment:16mm<br />Convergence adjustment:the optical axes of the lenses are aligned at a distance of 400mmm from the vertexes of the cornea(2mm each for right and left inward), interpupillary distance enabling convergence = 57mm to 80mm<br />Corneal distance device:2mm forward and 5mm backward from standard plane with scale<br />Effective field of view:19mm<br />Dimentsions(packing):580mm(L)x430mm(W)x250mm(H)<br />
