Outstanding features

Attractive delicate, beautiful design.
The precise function of the instrument means smoother operation in testing for myopia and astigmatism.
Cross cylinder and rotary prism provide the widest field of view.
Employs an unique mechanism in convergence system.
Testing range greatly widened by the big selection of auxiliary lenses provided.
Greater precision and durability provided with the oil less bearings.
By using together with the chart projector, a wide range of visual function (binocular vision, stereopsis, aniseikonia, and so on) can be examined.
High-grade coating executed on all surfaces of lenses.

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.

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 centres. Thus, this unique system insures perfection in testing.

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.
