摘要： An electromagnetic radiation system for directing an electromagnetic radiation beam (11) at a target (28) having a first arrangement (12) in which the radiation beam (11) is directed along a marking beam path that is within a marking range of the electromagnetic radiation system and a second arrangement (12, 15) in which the radiation beam (27) is directed along a different beam path (27) that is not within the marking range of the electromagnetic radiation system, wherein a positional relationship between the marking beam path (11) and the different beam path (27) satisfies a predetermined condition at the target (28) when the electromagnetic radiation system is at a predetermined distance (29) from the target (28).

摘要： There is provided a housing for a head for directing an electromagnetic radiation beam at a target, the housing comprising: an inlet for receiving a fluid; a cavity for enclosing at least one component for controlling the optical path of the radiation beam within the marking head; an outlet for the fluid; a first channel defining a first fluid path from the inlet to the cavity; and a second channel defining a second fluid path from the cavity to the outlet. When the at least one component for controlling the optical path of the radiation beam is enclosed within the cavity, the housing and the at least one component further define a third channel between the first channel and the second channel. The first channel, second channel and third channel are configured to isolate the fluid from the optical path of the radiation beam within the head. There is also provided a method of manufacturing a head for directing an electromagnetic radiation beam at a target.

摘要： A laser marking system (200) comprising first and second laser marking heads (201, 202) configured to mark a product (221, 222). The laser marking system comprises a first controller (231) associated with the first laser marking head (201) and a second controller (232) associated with the second laser marking head (202). The first and second controllers (231, 232) are configurable to receive data (205) indicating information to be marked on the product (221, 222), generate laser marking vectors based upon the received data, and control their associated laser marking head (201, 202) based on the laser marking vectors.
