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： The invention relates to a method for applying a marking within a marking area on an object, in which at least one light beam is emitted with light emitting means, scanning means are moved to deflect the light beam line by line over the marking area, while the light emitting means is switched between being activated or deactivated according to the marking to be applied. The method is characterized in that, for each start of a line movement of the light beam over the object, the scanning means is moved such that its deflection direction points at a line starting point outside the marking area and the scanning means is accelerated such that its deflection direction is accelerated from the line starting point towards the marking area, wherein the light emitting means is deactivated while the deflection direction points somewhere outside the marking area. The invention further relates to a corresponding marking apparatus.
