Refractometer parts and functions
WebThe examination is carried out with the help of a medical device - automatic refractor. During the procedure, a beam of infrared light emitted by the device passes through the pupil, reflected from the retina, is fixed by electronic sensors at the entrance and exit from the eye. WebMeasuring principle of refractometers The measuring principle of the didactic refractometer - which is also used in modern automatic refractometers - is based on the determination of the angle of total reflection, see Fig. 1. If the refractive index n1 of a medium and the critical angle αcrit are known they can be used to determine
