| 摘要 | There is disclosed apparatus for automatically calculating spectral bandwidth in a monochromator of the type having slit and wavelength drive mechanisms. A stationary scale member is scribed with indicating marks related to slit width. A sliding scale member is driven by the wavelength drive mechanism to slide juxtaposed with respect to the stationary scale member, the sliding scale member having a surface upon which are scribed indicating marks related to dispersion of the monochromator, the scribed marks of the sliding scale being calibrated with respect to the scribed marks of the stationary scale to indicate on the sliding scale the dispersion of the monochromator opposite a given slit width indication on the stationary scale. A moving indicator driven across the scribed surfaces of both scale members by the slit drive mechanism has a reference line to continuously indicate the monochromator slit width on the stationary scale and the corresponding dispersion on the sliding scale as the monochromator spectrum is scanned. | ||||||
| 权利要求 | 1. Apparatus for calculating spectral bandwidth in a monochromator of the type having a slit drive mechanism and a wavelength drive mechanism, comprising: a stationary scale member having a surface upon which are scribed indicating marks related to slit width of the monochromator; a sliding scale member driven by the wavelength drive mechanism to slide juxtaposed with respect to said stationary scale member, said sliding scale member having a surface upon which are scribed indicating marks related to dispersion of the monochromator, said scribed marks of said sliding scale being calibrated with respect to said scribed marks of said stationary scale to indicate on said sliding scale the dispersion of the monochromator opposite a given slit width indication on said stationary scale; and a moving indicator driven across the scribed surfaces of said scale members by the slit drive mechanism, said indicator having a reference line which moves over the scribe marks of both scale members to continuously indicate the monochromator slit width on said stationary scale and the corresponding dispersion on said sliding scale as the spectrum is scanned. 2. The apparatus defined in claim 1 wherein said scribed indicating marks on said stationary scale are calibrated logarithmically to include the range of the slit widths generated by the monochromator. 3. The apparatus defined in claim 2 wherein said scribed indicating marks on said sliding scale are calibrated logarithmically to indicate dispersion per unit dimension of slit width of the monochromator when said scribe marks of said sliding scale are observed opposite a scribe mark on said stationary scale indicating said unit dimension of slit width. 4. In a monochromator of the type having a slit drive mechanism and a wavelength drive mechanism, and wherein it is desirable to determine dispersion for a given slit width and wavelengtH, the improvement comprising: a slide rule mechanism having one fixed member and one sliding member, said sliding member being moved with respect to said fixed member by the wavelength drive mechanism, said fixed member and said sliding member having scale marks scribed thereon by which dispersion of the monochromator is indicated on said sliding scale opposite the corresponding slit width of the monochromator indicated on said fixed member; and a moving indicator placed over said slide rule and driven along said fixed and sliding members by the slit drive mechanism, for indicating on said fixed member the slit width of the monochromator and for indicating on said sliding member the dispersion of the monochromator corresponding to said slit width. |
