Title: Directional-light laser with a shutter-protection device
Inventor: SPIELVOGEL ERNST
IPC: H01S3/00
Filed: 1981-02-18
Abstract: A directional-light laser has a laser tube, which is arranged in a housing, and optics on the end light-outlet end of the laser tube, which optics fan the laser beam out. Using such a directional-light laser, in order to achieve harmlessness (in the sense of the standards and regulations) even at a relatively high light power, without incorrect handling being able to lead to the health of the operating personnel being damaged, it is provided that a shutter-protection device (4) be mounted on the optics (2), outside the light beam (5) and surrounding said light beam (5) on at least two sides. As a result of this shutter protection device (4), on the one hand the light beam is unchanged and is thus not weakened, while on the other hand protection is provided against external access on at least two sides so that, in particular, the operator can no longer move his eyes into that region of the light beam emerging from the laser tube in which the beam striking his eyes would cause damaging dazzling (blinding). The construction of the new directional-light laser is shown in two different views in Figs. 1 and 2. <IMAGE>
