INS-11010 | Manual Phoroptor

  Manual phoroptor model INS-11010. Provides highly accurate readings over a wide range. Used in measurements of Myopia, Astigmatism, Hyperopia, Presbyopia, Heterophoria, Range of Accommodation, Convergence, Aniseiconia, Stereopsis and Binocular Vision. Rapid, accurate readings on binocular visual balance. 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. In short, middle and long distance test, it is possible to have the optical axis of the lens and the line of patient vision match. Parameter: 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) 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) Cylinder axis:0-180°,5°steps Cross cylinder:±0.25D reversal,±0.50D optional Rotary prism:0?~20?,1? step PD adjustment:48mm~80mm,1mm step Forehead rest adjustment:16mm 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 Corneal distance device:2mm forward and 5mm backward from standard plane with scale Effective field of view:19mm Dimentsions(packing):580mm(L)x430mm(W)x250mm(H) Dimensions: 22 x 16 x 9 in / 56 x 41 x 23 cm Weight: 15 lb / 7 kg
