Metrological support to ophthalmological automatic refractometers
Tóm tắt
A test scheme is proposed that provides unified measurements in ophthalmological refractometry. The wavelength dependence has been determined for the optical strength (ametropia) of the optical measure for the radiations in the infrared and visible ranges for the nominal values defined by ISO standards.
