Assembly and method for detecting radiation

摘要

The invention relates to an assembly and method for detecting laser radiation which hits a disc (20, 28) sealing an opening (16, 18) of an enclosure, wherein at least one sensor (22) detecting the radiation is aligned having the radiation sensitive region (24) thereof on a circumferential edge section (26) of the disc, which is designed to be radiation-conducting. In order to enable secure monitoring both of the disc and of the enclosure, without a plurality of sensors being required, according to the invention, the enclosure has two walls (12, 14) spaced apart from each other and having openings (16, 18) which are sealed by the disc (20), the disc (20, 28) is arranged between the walls at the edge and the sensor (22) is arranged having the sensitive region (24) thereof between the walls, spaced apart from the disc or within an opening of the disc.

主权项

1. A device for detecting laser radiation from a radiation source, said device comprising:
a semi-transparent and radiation-conducting first element having a wafer-like construction; a protective device having two spaced-apart walls and openings through the walls; wherein said first element is disposed within the protective device; wherein said first element seals the openings in the protective device; wherein said first element has a through opening; and wherein a radiation sensor comprising a radiation receiving area is disposed in said through opening; wherein the radiation sensor is configured so that the radiation receiving area receives radiation conducted through the first element and radiation penetrating the protective device from outside of the first element.
