PURPOSE:To enhance the cooling efficiency of a cooling type photoelectric converter by mounting pin electrodes on a support plate for supporting infrared detector and inserting the pin electrodes into a socket provided partly in an inner cylinder, thereby increasing the vacuum degree. CONSTITUTION:An infrared detector 1 is placed fixedly on a support base 2. The base has side walls 2a, and electrode pins 4a, 4b are mounted on the outside. The electrode pins are electrically connected to the detector via metallized layers 5a, 5b and bonding pads 6a, 6b on the base. This structure A is contained in a double- walled cooling container, and is inserted fixedly into the pin electrode inserting inlet of a socket 9 mounted on a cooling base 8 in an inner cylinder B. In this manner, it can be assembled in vacuum, thereby eliminating the contamination, performing mounting in high vacuum degree and obtaining the infrared detector of high quality. |
