    Abstract: A measuring cell is formed of base plates joined together. A passage groove is formed on a joining surface of one base plate. Through-holes for introducing and discharging a fluid sample are formed on the other base plate, and the joining surface is provided with an optically opaque Si film as slits. Further, the joining surfaces of the base plates and the inner surface of the passage groove are covered with SiO2 films. Thus, a measuring cell having a sufficiently small passage sectional area, a high air-tightness, a chemically stable measuring chamber, and a high measuring sensitivity can be obtained.

    Abstract: A method of measuring and compensating stray light in absorbance analysis that use a multiple element array detector wherein one or more of the elements of the diode array are utilized to detect stray radiation in the absence of primary radiation including higher order diffracted radiation. In one aspect, the atmosphere is used to filter all primary radiation below a particular wavelength so that one or more array elements corresponding to detection below such wavelength can be dedicated to the detection of only stray radiation. Detection of higher order diffractions can be prevented by dividing the total spectrum into intervals and detecting these intervals in sequence. In another aspect, a diode array is designed to include additional elements along one side of the array outside the exposure of the primary radiation for the sole purpose of detecting stray radiation.

    Abstract: In a Littrow spectroscope including a concave mirror for reflecting light from a source, a diffraction grating for further reflecting the light reflected by the mirror, the grating being made rotatable to allow the mirror to re-reflect the light therefrom, and an exit on which the light re-reflected by the mirror is focused; a stray-light suppressor in the form of a strip is disposed in front of, and horizontally in parallel with the longitudinal central axis of, the mirror. The suppressor is held in front of the mirror at a distance of (L1-L2), where L1 is the distance between the mirror and the grating and L2 is the distance between the grating and the exit. The suppressor portion upon which the stray light from the diffraction grating impinges is tapered.

    Abstract: Methods for stray light measurement and compensation in spectrophotometers are disclosed. In one exemplary embodiment, stray light is determined as a convolution of a selected detected radiant power spectrum and a monochromator slit function. Such a stray light measurement may be made with or without the sample in an optical path between a source and detector within the spectrophotometer. When made with the sample in the optical path, the resulting stray light measurement may be used to compensate sample absorbance or transmittance measurements. In accordance with another embodiment of the present invention, sample absorbance or transmittance may be compensated in a method including measuring sample detected radiant power at a wavelength outside an interval of significant detected radiant power within which a sample measurement compensated for stray is desired.
