NIRCam is housed in the Integrated Science Instrument Module, to which it is attached physically by struts.[3][4][5][6] It is designed to operate at 37 Kelvin (roughly minus 400 degrees Fahrenheit), so it can detect infrared radiation at this wavelength.[3][7] It is connected to the ISIM by struts and thermal straps connect to heat radiators, which helps maintain its temperature.[3] The Focal Plane Electronics operated at 290 kelvin.[3]
