Rowland Diffraction Grating

Henry Rowland



Box marked, "Absolute Wave, Grating III" "This is an original Rowland grating and was used by Dr. Louis Bell (‘85) in measuring the wave length of sodium line 5896. For a very brief time the value of the wavelength was a world standard. The grating was used by Prof. Wm Rogers of Colby as a standard. It was acquired by me in 1898 and was brought here by me in 1899-1900" -G.F. Hull. It has 29000 spaces in four inches. For a further description of the # 3 grating see Louis Bell, "The Absolute Wavelength of Light" American Journal of Science, vol. XXXV, April 1888, p. 275.
