| 摘要 |
A device for irradiating a limited, defined area where uniform and intense irradiation is obtained of a sharply defined light field (7) of variable size, the light from a halogen lamp (1) or similar incoherent light source being directed by means of an elliptical mirror (2) towards one end surface (3) of a transparent rod (4) whose opposite end surface (6) is thereby uniformly irradiated and is imaged by a lens (7) in the area (9) which has to be irradiated.
