    Abstract: An optical absorption spectrometry system includes first and second light sources, a dichroic beam combiner and a wavelength selective module. The first light source emits first light having first wavelengths within a first wavelength range, and the second light source emits second light having second wavelengths within a second wavelength range different from the first wavelength range. The dichroic beam combiner includes a predetermined first reflectance/transmission transition region, the dichroic beam combiner being configured to transmit a first portion of the first light and to reflect a second portion of the second light to provide combined light. The wavelength selective module is configured to disperse the combined light received at an entrance aperture, to select a sample wavelength range of the dispersed light as sample light, and to output the sample light having the selected sample wavelength range from an exit aperture for illuminating a sample.

    Abstract: The invention relates to an Echelle polychromator and can be employed in instruments for the spectrophotometric investigation of radiation sources. It is characterized in that, connected in series with the polychromator, there is a dispersive and polychromatic illuminating device, which is formed from an entrance slit arrangement, collimator optics, prism and camera optics, the entrance slit arrangements of the polychromator and of the illuminating device consisting of a main slit for limiting the bundle in the grating dispersion direction and a transverse slit for limiting the bundle in the direction of the dispersion of the prism in the Echelle polychromator. The whole of the wavelength range, which is to be processed by the polychromator, is imaged completely with negligible aberration on the transverse slit of the Echelle polychromator as a spectrum of the illuminating device. The dispersion of the illuminating device runs in the direction of the transverse dispersion of the prism of the Echelle polychromator. The dispersion-induced geometric width of the spectrum of the illuminating device for the whole of the wavelength region that is to be processed by the polychromator is less than the width of the transverse slit of the Echelle polychromator. Parts of the bundle of rays of the spectrum of the illuminating device are blocked out by the transverse slit of the Echelle polychromator.

    Abstract: A spectra generator having an electrically programmable diffraction grating. There may be a broad band light source that emits light which is diffracted by the grating. Diffracting elements in the grating may be individually adjustable so that generation of a specific spectrum or spectra may be achieved. The diffracting elements may be adjusted according to electrical signals of a program from a computer. The generated synthetic spectra may be used for testing and calibration of spectrometers or other devices. Synthetic spectra may also be used for scene generation and other purposes.
