Features:1) New setup leveling mechanism2) Control of spherical power: a) Capable of measurement for the fullest range of +16.75D~0~-19.00D with the step of 0.25D b) Furthermore by application of an auxiliary lens of +0.12D, they are measured with step of 0.12D c) By turning the spherical power quick forwarding dial, necessary power can be obtained quickly with increment of 3.00D d) On the other hand by employing application of sphere auxiliary lenses of +10.00D and -10.00D e) The wider power of +26.75D~0~-29.00D can be measured3) Measurement of cylinder powers and axis: a) Cylinder power could be obtained within the wider range of 0~-6.00D with an increment of 0.25D b) Also by employing application of cylinder auxiliary lens of -0.12D, they arecounted with a 0.12D step c) Whilst by employing the attached cylinder auxiliary lens of -2.00D cylinderpower are capable for measurement within the wider range of 0~-8.00D4) 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. As options, ±0.37D,±0.50D cross cylinder lenses are available and can be exchanged conveniently 5) System: by laying down the convergence lever inside, a correct near pointmeasurement is capable
