(1)The new set up leveling mechanism.
(2)Control of spherical powers:
Capable of measurement for the fullest range of +16.750-0--19.000 with the step of 0.250.Furthermore by application of an auxiliary lens of +0.120,they are measured with the step of 0.120. By turning the spherical power quick forwarding dial, necessary powers could be obtained quickly with increment of 3.000.
On the other hand by employing application of sphere auxiliary lenses of +10.000 and -10.000,the wider powers of +26.750-0--29.000 could be measured.
(3)Measurement of cylinder powers and axis:
Cylinder powers could be obtained within the wider range of 0--6.000 with an increment of 0.250.
Also by employing application of cylinder auxiliary lens of -0.120,they are counted with an 0.120 step Whilst by employing the attached cylinder auxiliary lens of -2.000 cylinder powers are capable for measurement within the wider range of 0--8.000.Cylinder axis angles are graded from 0-1800 doubly with increment of 50 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 Iightly.As option ± 0.370, ± 0.500 cross cylinder lenses are available and could be exchanged conveniently.
(5)Rotary prism:
Measurable range for 20" with 1 step is available. By turning the prism unit the click at 90°and 180°will be beetled.
(6)Convergence system:
By laying down the convergence lever inside, a correct near point measurement is capable.
(7)Auxiliary lenses:
Described in the following specification.
Auxiliary lenses: By employing combinations of abundant auxiliary lenses and charts, various kinds of refractions are made.
