The SPIRE photometer has three arrays of bolometer detectors each dedicated to one of the instrument's three wavelength bands centred on approximately 250, 350 and 500 μm. This image shows the whole detector assembly for the 500 μm band. The 43 holes in this front view of the assembly are the entrances to feedhorns that direct the light onto the actual detectors: 43 bolometers lying behind the feedhorns in the assembly.
