[16005]
A professional for precise objective measurements of the corneal radius of curvature plus accurate measurements of the radius of curvature of contact lenses.
Compactly-designed and very easy to use by one hand operation.

FEATURES
CONTACT LENS MEASUREMENT
Replace the chinrest with the supporting column and place the contact lens holder, with the contact lens attached to it, on top of the column. It will be possible to measure the radius of curvature of the concave or convex face, depending on which faces the instrument, in the same manner as when measuring the cornea.

INTERNAL SCALE READING SYSTEM
Besides the mire images, the millimeter scales for the radius of curvature and the diopter scales for the corneal refractive power, of both vertical and horizontal axes are viewed at all times in the field of view, thus greatly speeding up measurements.

MEASUREMENT OF CORNEAL ASTIGMATISM
Horizontal displacement of the mire images indicates existence of astigmatism and the axis rotating handle is used to coincide the measuring head with the axis, after which the vertical and horizontal knobs are used to coincide the mire images, showing the great ease and simplicity of one position measurement.
One position measurement is not only more accurate but is truly effective in reducing measuring time and also helps promote patient's cooperation.
