Abstract: PURPOSE:To eliminate problems caused by the hysteresis of sensitivity characteristics of a photodetector at the time of photodetector switching by making light incident on the photodetector which is not used for measurement in measuring operation all the time. CONSTITUTION:A half-mirror Mh is used as a means which switches the 1st and the 2nd photodetectors P1 and P2 of a photometer. The half-mirror Mh is fixed slantingly by 45 deg. to the incident light, which is split to the 1st and the 2nd photodetectors P1 and P2 all the time. In this constitution, the light is incident on the photodetectors P1 and P2, specially, the photoelectron multiplier tube P1 throughout the measurement, so even when an in-use detector is switched from P2 to P1 on the side of a measuring circuit, the photodetection state is unchanged before and after the switching and there is no temporary variation of a 100% transmissivity line due to the hysteresis of the sensitivity characteristics. Consequently, an increase in measured value and drift before and after the photodetector switching are compressed and result with good reproducibility are obtained by the repetitive measurement.

Abstract: PURPOSE:To shorten a measuring time and to enhance measuring efficiency, by making it possible to use the data of a base line in two kinds of different measurements in common. CONSTITUTION:A specimen holder Ht for arranging a specimen for transmissivity measurement and a specimen holder Hm for arranging a specimen for reflection measurement are provided on a base plate B. At first, standard specimens for A-measurement and B-measurement are respectively set to beams F1, F2 and respective photometric values f1, f2 are collected as base line correcting data. Next, when A-measurement is performed, a specimen to be measured is set to the beam F1 and the standard specimen for B-measurement is set to the beam F2 as it is to collect the photometric values f1', f2' of two beams and, if A=(f1'/f2')/(f1/f2) is calculated at every wavelength, a characteristic value A is calculated. At the time of B-measurement, a specimen to be measured for B-measurement is set to the beam F1 and the standard specimen for A-measurement is set to the beam F1 and, if B=(f2''/f1'')/(f2/f1) is calculated according to same calculation formula, a characteristic value B is calculated. By this method, because correction data can be used in common, it is unnecessary not only to replace an attachment but also to again take a base line.

Abstract: PURPOSE:To prevent a squeeze tube from being damaged by stopping the operation of a squeeze pump by a sample detecting means when a sample is sucked to nearby the end of a tube on the side of the squeeze pump and storing a sample which is discharged from a nozzle in a waste liquid part during the discharging operation of the squeeze pump. CONSTITUTION:A sampler 1 is provided with sample containers 11 in odd columns and waste liquid containers 12 in even columns and a sample sucked by the operation of the squeeze pump 4 through a nozzle 2 is analyzed 6 through a light emitting part 17 and a detector 18 installed in opposition to each other across a flow cell 5 and then displayed 8. When the sample is sucked to nearby the end part of the side of the pump 4, a sample detecting means 9 detects the presence of the sample and outputs a squeeze pump operation stop signal to an operation control part 7 to stop the operation of the pump 4. The nozzle 2 is operated during the discharging operation of the pump 4 to discharge the sample to the respective waste liquid containers 12. Therefore, none of the sample enters the squeeze tube 13 of the pump 4 and the tube 13 is prevented from being damaged.

Abstract: PURPOSE:To prevent the appearance of the effect of local sensitivity on the light receiving surface of a light detector, by making it possible to selectively change-over a direct light receiving mode and an indirect light receiving mode. CONSTITUTION:A measuring apparatus is constituted of a spectrometer R, a rotary disc R, a speciment stand B to which a specimen S is set and the concave mirror M, luminous flux iris MS and replaceable lighr detector provided on the rotary disc R. At the time of a direct light receiving mode, a photomultiplier D is mounted on the rotary disc R as the light detector through a holder H and the light receiving surface thereof is positioned immediately behind the iris MS so that the reflected light from the specimen S is directly incident to the light receiving surface of the head end of the photomultiplier D. In the case of an indirect light receiving mode measuring mirror surface reflectivity, if an integrating sphere IS is mounted on the rotary disc R and the light incident window with the integrating sphere IS is positioned immediately behind the iris MS, diffusion reflection is repeated on the inner surface of the integrating sphere IS and uniform luminous intensity is imparted to the light detection window W of the integrating sphere IS and, therefore, the reflected light from the specimen can be received by the light detector without receiving the effect of the sensitivity irregularity of the light receiving surface.

Abstract: PURPOSE:To make it possible to perform the mounting, detachment and adjustment of a luminous flux converging jig independently of an optical system, by arranging the luminous flux converting jig to the outside of the specimen window of an integrating sphere. CONSTITUTION:A luminous flux converging jig 9 is mounted on the outside surface of the specimen window 4 of an integrating sphere 2 and a specimen S is mounted on the luminous flux converging jig 9 so as to be closely contacted with the outside surface thereof. The luminous flux converging jig is formed by providing a through-hole 11 in a thin phosphor bronz plate 10 to which black matter surface treatment was applied and fixing said plate 10 to a fixing metal fitting 12 with rivets as shown by the drawing and fixed to the screw hole 15 provided on the upper surface of an integrating sphere with a fixing screws 13. If many kinds of thin phosphor bronz plates 10 provided with through-holes 11 having different shapes and dimensions are prepared, the thin phosphor bronz plate 10 can be selected tailored to the contour of a surface region desired to be measured of the specimen. The through-hole 11 having an arbitrary shape and dimension is easily processed in matching relation to the specimen.

Abstract: PURPOSE: To make it possible to miniaturize the structure of the titled apparatus and to simplify measuring operation, by a method wherein a light source and a light measuring system is fixedly arranged and an integration sphere is rotated 180°C around one center line thereof.
CONSTITUTION: A light measuring system consisting of a light source, a light receiving element D and an iris F is arranged so as to fix the position thereof with respect to an integration sphere I having a specimen window W
s , a specimen light outlet window W
os and a reference light outlet window W
or and said integration sphere I is provided so as to be made rotatable 180° around an axis A
x . In performing measurement, the entire amount I
r of light taken out from the window W
or is measured and, after the integration sphere I is rotated 180°, the amount I

Abstract: PURPOSE:To mix multiple light fluxes with a simple construction in a small size by receiving light on a light receiving surface at the rear end thereof after incident light from a symmetrical roof section having the tip thereof roughly orthogonal is reflected on the inner surface of a cylindrical section. CONSTITUTION:Multiple light fluxes divided into two parts or so from the same monochrome light source separately transmit a sample and control cells S and R and are reflected on a reflective inner surface of a cylinder via transmitting light diffusion plate 2 and 2' in which tips of a cylinder 1 cross roughly at the right angle to form a symmetrical roof section. Then, the lights are mixed and enter a light receiving surface of a photomultiplier P provided at the rear end of the cylinder 1. This symmetry allows the multiple light fluxes to be mixed at a high utilization efficiency with a simple construction in a small size.
