Outstanding features

  1. Attractive delicate, beautiful design.
  2. The precise function of the instrument means smoother operation in testing for myopia and astigmatism.
  3. Cross cylinder and rotary prism provide the widest field of view.
  4. Employs an unique mechanism in convergence system.
  5. Testing range greatly widened by the big selection of auxiliary lenses provided.
  6. Greater precision and durability provided with the oilless bearings.
  7. By using together with the chart projector, a wide range of visual function (binocular vision, stereopsis, aniseikonia, and so on) can be examined.
  8. High-grade coating executed on all surfaces of lenses.
1 Level adjustment
Level adjustment can be made easily in one-touch operation by using the leveling knob and level.
2 Interpupillary adjustment
The wide range of adjustment of 48mm through 80mm and easy to read scale in 1mm graduation.
Convenient knobs, located on both sides, enable smooth and rapid adjustment.
3 Adjusting Sphere Power Readings
Adjustment can be made exactly from -19.00D to +16.75D in 0.25D steps and the sphere power rapid feed dial allows rapid eye examination per ±3.00D. With accessory lenses, it is possible to read upto ±0.12D. Also, the auxiliary lenses ±10.00D(option) are available to extend adjustment range upto -29.00~ +26.75D.
4 Adjusting Cylinder Power and Axis
The cylinder lens graduated in 0.25D steps allows adjustment upto 0 ~ -6.00D and with accessory lens -2.00D, it is possible to extend adjustment range upto -8.00D. The cylinder axis can be adjusted upto 0°~ 180°in 5°steps. Each adjustment can be made rapidly with two konbs on the same axis.
5 Cross Cylinder (±0.25)
The cross cylinder loupe, through a special mechanism synchronized completely with the cylinder lens axis control konb, automatically rotates to a corresponding axis each time you change the cylinder lens axis.
6 Rotary Prism
The readings can be taken accurately upto 20△ in 1△ scale graduation. Also, the click stop permits you to measure horizontal and vertical strabismus and heterophoria. Using both right and left prisms makes you possible to take readings upto 40△ test eye balance.
7 Built-in Auxiliary Lenses
The cross cylinder loupe, through a special mechanism synchronized completely with the cylinder lens axis control konb, automatically rotates to a corresponding axis each time you change the cylinder lens axis.
8 Convergence System
Precision measurement is possible with lens setting to suitable angle for near testing (by closing the convergence lever inward) as well as distance (by opening it outward). This converges the optical system coincident to the convergence of the patient’s eyes and the patient can always look through the correct optical centers. Thus, this unique system insures perfection in testing.
9 Corneal Aligning Device
Through the sight, align the corneal vertex of the patient and set the patient’s cornea in correct position (at 12mm from the view tester lenses).
Measurement should be made at ”0” position of the scale.
10 Near Point Scale and Chart
The scale is graduated in “lnch”, “Centimeter” and “ Diopter”. It can be set at distance you like for use and when not in use, it can be stored in standing position. The Near Point Chart contains a rotatable disc with 12 kinds of tests at both sides. The scale is 67cm in length.
11 Forehead Rest
The knob adjusts distance between cornea and lenses and makes positioning of the patient’s forehead very smooth..
