Abstract: PURPOSE:To achieve a high-speed measurement by a near-infrared analytical apparatus, to increase the measuring accuracy of the apparatus and to increase the stability of the apparatus. CONSTITUTION:An analytical system wherein a tungsten halogen light source 1, a diaphragm 2 which narrows a measuring light flux from the light source, a condensing optical system 3 which condenses the measuring light flux and which guides it to a measuring part and an integrating sphere 6 for the measuring part on which a sample is placed is arranged on a base 11. An entrance slit 15 for a spectroscope part 40 is arranged on the bottom face of the integrating sphere 6 for the measuring part. A diffraction grating 12 which diffracts and disperses a light flux incident from the entrance slit 15, an array-shaped detector 14 and a reflecting mirror 13 which bends the light flux diffracted and dispersed by the diffraction grating 12 and which forms the image of the light flux, in a dispersed manner, on the face of the array- shaped detector 14 are installed in the spectroscope part 40. When signals from the array-shaped detector 14 are accessed sequentially, a wavelength can be scanned electrically, the high accuracy of the wavelength can be maintained for a long time, and a measurement can be performed at high speed. When the measurement is repeated and its data are integrated, a measuring noise is reduced and the measuring accuracy of the title apparatus can be enhanced.

Abstract: PURPOSE:To provide a spectral transmissivity measuring device by means of the two-light-flux method of a color separation prism. CONSTITUTION:A photometry means I is installed at a place where a light beam S incident on a specimen does not enter the means I when the beam is directed to go straight, and two movable mirrors 9, 10 are arranged between the specimen and the photometry means. The position of the mirror 9 and the direction of the mirror 10 are altered so that the beams of light in the respective cases are directed to the photometry means I according to four measuments, 100% transmission photometry without the specimen and three-color transmission photometry. Since the mirrors 9, 10 are also used at the time of 100% transmission photometry and the three-colors transmission photometry, the influence of the mirrors 9, 10 is offset and absolute transmissivity can be found when the transmissivity is calculated.

Abstract: PURPOSE:To obtain an efficient transmission mechanism suitable for the driving of a sign bar, by meshing the spherical body provided to the leading end of the sign bar with the feed screw carved in the rotary shaft driven by a motor. CONSTITUTION:A feed screw 3 is directly carved in the rotary shaft 2 directly connected to a motor 1 and the spherical body 7 provided to the leading end of a sign bar 6 is meshed with the groove part of the screw.The movable body 8 holding the motor 1 and the rotary shaft 2 is supported so as to slide in the direction right-angled to the rotary shaft 2 by a guide 17 and lightly energized toward a diffraction lattice 4 by a spring 9. When the motor 1 is rotated by an input pulse and the rotary shaft 2 is rotated, the spherical body 7 moves on the circumference of the circle around the rotary shaft 5 of the diffraction lattice 4 and has the displacement in the direction right-angled to the rotary shaft 2. Since the movable body 8 is energized toward the diffraction lattice 4 at this time, the rotary shaft 2 follows the sign bar 6 and, since the spherical body 7 and the screw 3 are meshed under definite contact pressure, the possibility of generating backlash is eliminated.

Abstract: PURPOSE:To measure a large-sized sample and a deformed sample which can not be stored in a sample chamber directly by installing a prepositioned optical system in the sample chamber detachably, and reflecting and emitting out one of two pieces of luminous flux and making the other incident on an optical fiber. CONSTITUTION:When the prepositioned optical system P is installed in the sample chamber, luminous flux for a sample which enters the sample chamber SC from a light source part M is reflected by a mirror M2 by 90 deg. to enter an external sample chamber OS, and then travels in the center of the chamber to strike on an integrating sphere IS. Reference lumious flux, on the other hand, is reflected by a mirror M1 by 90 deg., passed through a lens L1, and converted on the light incidence terminal of an optical fiber F through another window of a front panel Q. The optical fiber F runs along the side wall internal surface of the external sample chamber OS and the reference light is incident on the integrating sphere IS almost at right angles to the sample luminous flux. Further, a photodetector D2 is arranged opposite the light guide-out window of the integrating sphere IS and the photodetection unit is fitted slidably on a guide almost at right angles to the sample luminous flux incident on the integrating sphere IS.

Abstract: PURPOSE:To prevent the lowering in the positioning reproducibility of a diffraction lattice caused by the heat generation of a motor, by interposing a heat insulating coupling mechanism between a lever pivotal support part and a turntable driving motor. CONSTITUTION:A wavelength drive table 2 and an extending part 11 are connected by a heat insulating washer 12 and a lever 9 is pivotally supported by the extending part 11. When the distance between the pivotal support center of the lever 9 and the rotary shaft of a motor 6, that is, the center of rotation of a turntable is set to L0 and the distance from the center of rotation to the coupling part of the extending part 11 and the drive table 2 is set to L, L0>L is formed. The heat from the motor 6 is conducted to the drive table 2 but almost not conducted to the extending part 11 by the heat insulating washer 12. Therefore, the distance L changes by thermal expansion but the extending part does not almost generate thermal expansion. When thermal expansion per unit length is set to (e), the change of L0 by thermal expansion is Le and L

CONSTITUTION:A diffraction grating 3 is set at the ultraviolet ray area while a high-order cut filter 5 is set at a desired position and with the lighting of a heavy hydrogen lamp L1, a pulse motor PM1 is rotated. The light of the lamp L1 is detected by a photometry section (c) via an inlet slit 2, the diffrac tion grating 3, an output slit 4, a filter 5 and a reference cell REF. The position indicating the maximum output is determined reading the output into a CPU8. the same measurement is performed turning a rotary disc 6 by 100 deg. to define the optimum position. Then, the position of making slits 15 and 4 coincide rotating a pulse motor PM3 to define the positions of filters F1, F2 ... Likewise, required setting is made for a halogen lamp F2.

Abstract: PURPOSE:To make incident the max. quantity of light to an inlet slit at all times by driving a rotary table for changing over light sources, detecting the point where the photodetector output of a spectrophotometer with respect to both light sources indicates the max. value and making the initial setting of the light source position. CONSTITUTION:The spectrophotometer is constituted of a lamp L1 for a visible region and a lamp L2 for a UV region installed on the rotary table 1 driven rotationally by a pulse motor PM1, a spectroscope 3, a diffraction grating 4, a sample cell SAM, a reference cell REF, an analog-to-digital converter 5, a CPU6, a RAM7, etc. The diffraction grating is first set at the prescribed wavelength within the UV region in the case of setting initially the light source position. Only the lamp L2 is thereafter lighted up and the position where the value of the signal VS on the cell REF side indicates the max. value is detected while the table 1 is driven. The diffraction grating is then set at the prescribed wavelength within the visible region and thereafter only the lamp L2 is lighted up and the position where the value of the signal VS is max. is determined by the same procedure. The motor PMI is thereafter controlled by the position data obtd. in the above-mentioned manner.
