Lensmeter LM 190
Manual Lensmeter of external reading
This device is suitable to test the diopters of:
-spherical lenses of ophthalmic lens
-axis(axle) of astigmatism of cylindrical lens
-diopter of the prism and diopter of the cornea - contact lens
The ocular one is provided with a unit of approach which range of approach is of + 5D to be adapted to the different visions of the different operators.
The retcle is divided with the scale of measurement and the dividing disc of the degree of the prism.
The entire degree of the prism is read directly of the scale of measurement and of the decimal scale estimated according to the degree on the scale of measurement.
Ranges of measurement of diopters: Minimal value of the scale:
Axis of the astigmatism of the cylindrical lens:
Diopter of the prism:
Angle bases of the prism:
Regulator of the ocular visibility:
Size of the lens:
