Abstract
The invention relates to a calibration radiation source comprising the following: a housing (2) having an opening (12), a board (22) held in the housing (2), a semiconductor radiation source (18) mounted on the board (22) for generating a light beam, and an exit opening support element (14) having, in the area of the opening (12), a light exit opening (15) through which the light beam radiates outwards from the housing (2). The exit opening support element (14) is decoupled from the housing (2), and is attached to the board (22) of the semiconductor radiation source (18).

A calibration light source comprising:
- a housing (4) having an opening (12),
- a board (22) held in the housing (4),
- a semiconductor light source (18) held by the board (22), the semiconductor light source to generate a light beam,
- an exit opening support element (14) having, in an area of the opening (12), a light exit opening (15), functioning as an aperture through which the light beam generated by the semiconductor light source (18) radiates outwards from the housing (4),
- an active cooling device (30) connected to the board (22), the active cooling device to cool the semiconductor light source (18),
- a first thermally conductive connecting element (28) connecting a cold side of the cooling device (30) with the board (22) of the semiconductor light source (18) to convey heat away from the semiconductor light source (18) and to the cooling device (30), a thermally isolating holder (38),
- a second thermally conductive connecting element (34) connected to a hot side of the cooling device (30), the second connecting element (34) held in the housing (4) by a thermally isolating holder (38),
- wherein the active cooling device (30), the first thermally conductive connecting element (28) the exit opening support element (14) and the semiconductor light source (18) are suspended in the housing via the thermally isolating holder in an area adjacent to a portion of the second connecting element (34) toward an end opposing the active cooling device (30), wherein the exit opening support element (14) is attached to the board (22) of the semiconductor light source (18), and wherein a gap (13) is provided between a sidewall of the exit opening support element (14) and an inner edge of the opening (12).
