| 英文摘要 | PURPOSE:To reduce the cost and to avoid waste of luminous amount by sealing an opening part of an externally surrounding means with a beam shaping cylindrical lens and a heat insulating member. CONSTITUTION:A projected cylinder of a housing 120 of a light source unit is inserted externally to a hole 40A of an optical system housing 40 and screwed to the housing 40. A holding means 30 is screwed to the housing 40, so as to connect the housing 40 and the cylindrical lens 12 in terms of heat conduction. In this case, the heat insulating member 36 is pressed into contact with the tip of the cylinder of the housing 120. Thus, the opening part of the externally surrounding means is sealed by the cylindrical lens 12, a seal 32, a lens retainer 34 and the heat insulating member 36. In lighting a semiconductor laser 100, the laser beam is made in parallel by a collimator lens, incident in the cylindrical lens 12 and the emitted laser beam is subject to required beam shaping by the lens 12. |
