Zusammenfassung: | The device comprises optically interconnected components such as an ultraviolet pulsed laser operating at a wavelength of 223 nm, a uniform light beam former, a slotted mask with its rotation drive, and a means for forming the image of the slotted mask on a surface of the cornea of the eye. The slotted mask having at least two slots shaped as identical lobes provides in rotation for uniform axysymmetric distribution of ultraviolet radiation over the exposed surface of the cornea. Arranged at the optical outlet of the former are a unit used to monitor energy density of ultraviolet radiation and a microscope. |
