Abstract
Disclosed is an instrument including a multipath, monolithic optical component, made up of a portion of a transparent material between two opposite faces of the component. One of the two faces of the component is formed by a first refracting surface, and the other face includes several second refracting surfaces which are juxtaposed. Each optical path of the component is formed by one of the second refracting surfaces in combination with a corresponding portion of the first refracting surface. One such component is suited for being part, within the instrument, of a detection module with multiple optical paths arranged in parallel, with a matrix photodetector shared by the optical paths. Such a detection module may be compact enough in order to be integrated into a cryostat cold screen, improving cooling thereof, and may be combined with an objective in order to form an instrument with multiple optical paths.
