auto refractometer refraktometer ARK 7800L alat periksa mata otomatis

auto refractometer (ARK-7800L) Features. When adjust the automatic measure method , and move the machine head to left eye area, the machine will automatic adjust machine position , and automatic tracking, and auto measure till finish . After finished left eye, operator should move the machine head to right eye area, then the machine will again auto tracking, auto measure , till finish , and will auto print , auto cut paper . Easy operate, especially for the biginner use. New optical system, unique imaging impression Hartman imaging analyzing and processing technology, accurate measurement result TFT touch screen, can move front and back freely Motorized chinrest Auto paper-cutting printer Auto tracking and focusing during measuring Technical Parameters Vertex Distance(VD): 0.0, 12.0, 13.75, 15.0 SPH: -30.00D~+25.00D(VD=12mm, 0.01, 0.06, 0.12, 0.25 Unit) CYL: 0.00D~±10.00D(0.06, 0.12, 0.25 Unit) Axis(AX): 1°~180°(1° Unit) Cylinder Form: -, +, ± Pupil Distance(PD): 10~86mm Minimum Pupil Distance: 2.0mm Measuring Time: ∠0.5s Pupil Diameter: 2.00~8.00mm Measuring Light Energy: ∠30uw(Insure measuring safety) Radius of Curvature: 5.0~10.0mm(0.01mm Unit) Corneal Power: 33.00D~67.00D(In case that the corneal equivalent refractive power is 1.3375) Corneal Astigmatism: 0.00D~-15.00D(0.06D/0.12D/0.25D Unit) Data Storing: Each 10 measured values of left eyes and right eyes Axis: 1°~180° Chart: Auto fog Monitor: SHARP 7″ TFT LCD touch screen(Angle of view adjustable) Built-in Printer: 57mm thermal printer, auto paper-cutting Electric Power: AC 100~250V, 50/60Hz N.W.: 22kgs G.W.: 26.5kgs Dimensions(packing): (L)680mmX(W)400mmX(H)640mm
