Strip photomicroscopy

The strip photomicroscopy method is the same as the ordinary spot (round light) photoscope, and can be used as an ordinary plane photoscope; the difference from the general photoscope is that the light bands are placed on different meridians and the observations are perpendicular to each other There are no differences in the characteristics of the light bands, so as to determine the presence or absence of astigmatism. Various types of astigmatism can be measured by the axis of the optical axis.
