Level adjustment

Level adjustment can be made easily in one-touch operation by using the leveling knob and level.

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.

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.

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 knobs on the same axis.

Cross cylinder (±0.25)

The cross cylinder loupe, through a special mechanism synchronised completely with the cylinder lens axis control knob, automatically rotates to a corresponding axis each time you change the cylinder lens axis.

Rotary prism

The readings can be taken accurately upto 20 ∆ in 1 ∆ scale graduation. Also, the click stop permits the measurement of horizontal and vertical strabismus and heterophoria. Using both right and left prisms makes it possible to take readings upto 40 ∆ test eye balance.

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 helps ensure the quality of testing.

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.

Near point scale and chart

The scale is graduated in “lnch”, “Centimeter” and “ Diopter”. It can be positioned at any preferred distance for testing. 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.

Forehead rest

The knob adjusts distance between cornea and lenses, and makes positioning of the patient’s forehead very smooth.
