摘要
The Hectochelle will be a fiber-fed, multi-object spectrograph for the post-conversion MMT which will take 255 simultaneous spectra at a resolution of 32,000-40,000. The absolute efficiency, including optical fiber losses, is predicted to be 6%-10%, depending on the position of a line within a diffractive order. In one hour, features with 60 m Angstrom should be resolved in m(R) = 18 stars with a signal to noise of 10.
