1. The new set up leveling mechanism.
2. Control of spherical powers: Capable of measurement for the fullest range of +16.75D~0~19.00D with the step of 0.25D. By turning the spherical power quick forwarding dial, necessary powers could be obtained quickly with increment of 3.00D.
3. Measurement of cylinder powers and axis: Cylinder powers could be obtained within the wider range of 0~-6.00D, with an increment of 0.25D. Also by employing application of cylinder auxiliary lens of -0.12D, they are counted with an 0.12 step. Whilst by employing the attached cylinder auxiliary lens of -2.00D, cylinder powers are capable for measurement within the wider range of 0~-8.00D. Cylinder axis angles are graded from 0~180° doubly with increment of 5° cylinder axis angle.
4. Cross cylinder: By turning the cylinder axis knob, the cross cylinder will be moved by the peculiar synchronized mechanism. The cross cylinder will be turned over by turning the cross cylinder knob lightly.
5. Rotary prism: Measurable range for 20Δ with 1Δ step is available.
6. Convergence system: By laying down the convergence lever inside, a correct near point measurement is capable.
7. Auxiliary lenses: By employing combinations of abundant auxiliary lenses and charts, various kinds of refractions are made.
