Abstract
An apparatus comprising a heat-sensitive device (F); a radiative element (RE), the radiative element in operation generating first electromagnetic radiation (ER), the first radiation propagating towards the heat-sensitive device; and a radiation-shielding device (20) arranged between the radiative element and the heat-sensitive device such that, in operation, the first radiation impinges on the radiation-shielding device. The radiation-shielding device comprises a first shield element (21) having a first fluid channel (215) arranged therein, the first shield element having a first surface (213) and a second surface (214), the first surface being arranged closer to the radiative element than the second surface; and a second shield element (22) having a second fluid channel (225) arranged therein, the second shield element having a third surface (223) and a fourth surface (224), the third surface being arranged closer to the radiative element than the fourth surface. The first shield element is arranged closer to the radiative element than the second shield element and the second shield element is arranged closer to the heat-sensitive device than the first shield element, the first s…
