| 摘要 |
<p>The invention relates to an optical projector producing an intense visible, infrared or ultraviolet, radiation beam to be used as a light source, heating source or source for topic thermal treatments and controlled artificial tanning of human body skin, respectively, being meant to be employed in particular in the optical industry. The optical projector is provided with a circular optical source (1) mounted in the focus point of a reflecting piece (2) with silver-coated surface (S1) ensuring the radiation concentration on a central profiled piece (3, 3', 3") which has, in its turn, a conical internal surface (S3, S5, S8) with a right angle-shaped apex which, by total or partial reflexion, deflects the light propagation in a parallel beam.</p> |
