Dispersing
System
The Wadsworth 1.5 meter stigmatic concave grating mount, with a 30,000 line/inch ruling (G) gives 5.3A/mm and good - - ^ - . , intensity from 2300 to 4300 A. Collimating mirrors (Ml, M2) produce two similar full intensity spectra, one above the other. This feature (patent applied for) 1) makes possible measurement of two lines very close together, one in each spectrum; 2) doubles space available for photomultipliers; 3) makes possible employment of photomultipliers directly behind most lines without mirrors.
