Title: Optical apparatus for analysing the spectrum of a light source
IPC: G01J3/12
Filed: 1977-07-07
Abstract: 1530547 Spectrometer INTERNATIONAL BUSINESS MACHINES CORP 7 July 1977 [19 July 1976] 28503/77 Heading G2J [Also in Division G1] A spectrum analyzer has a set of interference filters mounted around the edge of drum so as to allow a wavelength scan of light incident on the filters to be performed by rotating the drum. Each filter is mounted so that one face is normal to a drum radius, and the light incident on the filters follows a radial path; the effect of this is to change the angle of incidence of the light on each filter as it is moved by the drum, thus changing the wavelength which it passes (a known feature of interference filters). Thus with a set of filters 28 as in Fig. 4 having different nominal wavelengths, the wavelength passed varies not only from filter to filter but also varies smoothly as any given filter is moving through the radial path of light from guide 40. Fourteen filters may be used to cover the visible spectrum. The light may come from a sample to be investigated, Fig. 2 (not shown), guides 40 and 46 directing the light through the filters and to a photo-multiplier. The associated circuitry receives a timing signal each time a new filter 28 enters the light path, and also receives signals representing increments of drum motion. This enables the circuitry to calculate the wavelength being passed at any moment of drum rotation. The photomultiplier output is digitized and then analyzed to determine the properties of the sample against wavelength.
