At the present time only about 90 $%$of the total optical path (source to detector) is being evacuated. However, it has been possible to work in regions formerly inaccessible to our high resolution unevacuated instrument. Some of the optical and mechanical problems have been solved in a rather novel and satisfactory manner. en_US dc.format.extent 67297 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title A FIVE-METER DOUBLE PASS EVACUATED GRATING $SPECTROGRAPH^{*}$ en_US dc.type article en_US
