摘要 |
<p>The device (1) has an LED- radiation source with a reflector (7) and a fiber-optic light guide (3) for conveying a coupled light radiation onto a tooth area to be irradiated. The light guide has shell-core fibers with a section that enlarges an angle of aperture for the light radiation on its light entering end. Additional optical units that enlarge the aperture are connected upstream to the light entering end for bundling light.</p> |
