The optical chain of the spectroscopic X-Ray telescopes aboard the Constellation-X spacecrafts employs a reflective grating spectrometer to provide high resolution (E/ΔE approx. 400) spectra for multiple spectra as a slitless spectrometer in the spectral feature rich, soft X-Ray band (0.2-2.3 keV). As a part of the spectroscopic readout array, we provide a zero-order camera that images the sky in the soft band inaccessible to the microcalorimeters. Technological enhancements required for producing the RGS instruments are described, along with prototype development progress, fabrication and testing results.
