ILLUMINATION BEAM ADJUSTMENT APPARATUS AND ILLUMINATION APPARATUS |
| 摘要 |
An illumination beam adjustment apparatus is disclosed. The apparatus comprises a housing (4), a plurality of first optical elements (12) fixed relative to the housing and adapted to receive and transmit electromagnetic radiation and adjust the beam angle of a beam of electromagnetic radiation passing therethrough, and a second optical element (14) removably mounted relative to the housing and adapted to receive electromagnetic radiation from the first optical elements and transmit electromagnetic radiation. The second optical element is adapted to adjust the beam angle of a beam of an electromagnetic radiation passing therethrough. |
