This optical device offers the examiner the possibility of a sharply defined slit-shaped light beam, whose width can be varied to focus on the eye. At the same time he has the opportunity to look at this through a light microscope. The magnification of the microscope is variable with most devices and usually ranges from 6- to 30-fold.
Through various exposure methods (diffuse, direct, focal, indirectly, regressed, side, etc.) and variable light slit widths, it is possible to inspect almost all front, middle and rear portions of the eye to far located in the peripheral regions of the retina. For some investigations are additional aids, such as a three-mirror lens, necessary.
