The dispersed light from the faceted grating is coupled to a linear array of 160 bolometers via 8 waveguide bend blocks. Each block mounts 20 detectors above and below the plane of the parallel plate waveguide in an alternating fashion, maximizing spacing between adjacent bolometers. The waveguides have a constant rectangular cross section and use curved waveguide feeds. The blocks are fabricated by bolting 21 slices together.
