Item and range of measurement

The value in ( ) is with accessory lens or auxiliary lens attached

Myopia

0 to –19.00D in 0.25D step (0.12D step)

Hyperopia

0 to +16.75D in 0.25D step (0.12D step)

Astigmatism

0 to –6.00D (– 8.00D) in 0.25D step (0.12D step)

Cross-Cylinder

±0.25D (±0.37D and ±0.50D as option)

Phoriaandvergency

20∆ to 0 to 20∆ by 1∆ step

Inner 40∆

Outer 40∆ (50∆)

UpwardandDownward 40∆ (46∆)

Nearvision test

Main optical axes of both lenses converges by means of a tilt mechanism at 40cm in front of the eyes at 64mm P.D. If P.D. for far vision is less than 54mm, converging operation stops.

Binocularbalance test

Rotary prism and polarizing lens methods are available.

P.D.

48 to 75mm by 1mm step

Level adjustment

More than 4.5° for right and left banks

Dimensions

335 (at 64mm P.D. setting) x 97 x294mm

Weight

4.5 kg
