It is intended for measurement of a refractivity of an eye, supplied with function of measurement of curvature of a cornea.
It is applied in ophthalmologic departments of medical institutions. The device is supplied with the mechanism of automatic alignment; therefore operation of simple measurement is available. Besides, the device is supplied with function of automatic measurement which automatically begins measurements when the device is entered into a zone of measurements. As soon as automatic measurement begins, infrared radiation for the analysis of a refractivity and curvature of a cornea of an eye is reflected.
