a lens holder comprising a wall surrounding a cavity; and an image sensor arranged at a bottom of the cavity, wherein the image sensor is faced towards the lens unit, wherein the lens member is at least partly inserted into the cavity, wherein the barrel of the lens member defines a channel which extends inside a wall section of the barrel of the lens member in parallel with the longitudinal lens member axis and which has a first end opening facing a field of view of the lens arrangement, and wherein the lens arrangement comprises an emitter arranged to emit electromagnetic radiation to an area located in the field of view of the lens arrangement via the channel and the first end opening. ### Claim 2 (depends on 1) The lens arrangement according to claim 1, wherein the channel comprises a light guide arranged in the channel. ### Claim 3 (depends on 1) The lens arrangement according to claim 1, wherein the emitter is arranged to emit electromagnetic radiation in the form of at least one of: UV light, IR light, radar radio waves, visible light, or laser light. ### Claim 4 (depends on 1) The lens arrangement according to claim 1, wherein the channel further comprises a second end opening. ### Claim 5 (depends on 4) The lens arrangement according to claim 4, wherein the second end opening is point-shaped; and wherein the first end opening has a semi annular or annular shape. ### Claim 6 (depends on 4) The lens arrangement according to claim 4, further comprising a connector providing a communication between the emitter and the second end opening of the channel. ### Claim 7 (depends on 4) The lens arrangement according to claim 4, wherein the second end opening is faced towards the emitter. ### Claim 8 (depends on 7) The lens arrangement according to claim 7, wherein the emitter is arranged on or adjacent to an image sensor arranged at a bottom of the cavity. ### Claim 9 (depends on 1) The lens arrangement according to claim 1, wherein the lens member is slidingly insertable into the lens holder. ### Claim 10 (depends on 9) The lens arrangement according to claim 9, wherein the barrel comprises a wall section in the form of a lens member protrusion extending radially outwardly; and wherein the channel extends inside the lens member protrusion. ### Claim 11 (depends on 1) The lens arrangement according to claim 1, wherein the lens member is releasably attached to the lens holder. ### Claim 12 A camera device comprising a lens arrangement, the lens arrangement comprising: a lens member comprising a barrel enclosing a lens unit and extending along a longitudinal lens member axis; a lens holder comprising a wall surrounding a cavity; and an image sensor arranged at a bottom of the cavity, wherein the image sensor is faced towards the lens unit, wherein the lens member is at least partly inserted into the cavity, wherein the barrel of the lens member defines a channel which extends inside a wall section of the barrel of the lens member in parallel with the longitudinal lens member axis and which has a first end opening facing a field of view of the lens arrangement, and wherein the lens arrangement comprises an emitter arranged to emit electromagnetic radiation to an area located in the field of view of the lens arrangement via the channel and the first end opening. ### Claim 13 A lens arrangement for a camera device, the lens arrangement comprising: a lens member comprising a barrel enclosing a lens unit and extending along a longitudinal lens member axis; and a lens holder comprising a wall surrounding a cavity, wherein the lens member is at least partly inserted into the cavity, wherein the barrel of the lens member defines a channel which extends inside a wall section of the barrel of the lens member in parallel with the longitudinal lens member axis and which has a first end opening facing a field of view of the lens arrangement, wherein the lens arrangement comprises an emitter arranged to emit electromagnetic radiation to an area located in the field of view of the lens arrangement via the channel and the first end opening, wherein the channel further comprises a second end opening, and wherein the lens arrangement further comprises a connector providing a communication between the emitter and the second end opening of the channel.
