FIELD: physics.
SUBSTANCE: cooled photodetector base is made of material having a thermal expansion coefficient equal to or close to that of the cooled element and, in order to reduce cooling non-uniformity, an opening passes through the entire length of the base, wherein a heat pipe is placed in said opening, and the remaining gap between the heat pipe and the opening of the base is filled with gallium to form a mechanical bond with good thermal conductivity.
EFFECT: invention considerably reduces the temperature gradient when cooling large photodetectors made on both a single substrate and assembled from multiple units.
