13 September 2011The opto-mechanical design of the Colorado High-resolution Echelle Stellar Spectrograph (CHESS)
We present the Colorado High-resolution Echelle Stellar Spectrograph (CHESS) sounding rocket payload. The
design uses a mechanical collimator made from a grid of square tubing, an objective echelle grating, a holographically-ruled
cross-disperser, a new 40 mm MCP with a cross strip anode or a delta-doped 3.5k x 3.5k CCD detector. The optics
are suspended using carbon fiber rods epoxied to titanium inserts to create a space frame structure. A preliminary design
is presented.
