The photodetector has a sensor (3) mounted on a table (2) and connected to electrical leads. Vents (22, 23) for passage of electrical leads are arranged between the table and a shield (10), in which the shield is placed on the table. A Joule-Thomson cooler (4) cools the table and the shield by convection. The table has orifices through which a cooling flow passage communicates with a cavity (14) for cooling the shield. |
