Abstract: PURPOSE:To achieve a smaller size and a lighter weight facilitating the operation, by arranging a plurality of mirrors detachable at a fixed position so that the light emitted from a spectroscope is reflected with the mirrors sequentially to be incident on a light receiving element while they can be replaced with a sample. CONSTITUTION:Luminous flux emitted for a spectroscope through an emission slit 1 is made incident on a flat mirror MR1 at 45 deg., then on a flat mirror MR3 at 60 deg. through a mirror MR2 and the reflected light thereof is made incident on a photo detector D. The flat mirrors MR1 and MR3 are made detachable and can be replaced with a sample to be measured or a reference sample. When measuring the gloss at 45 deg. in the incident and reflection angle, the flat mirror MR1 is replaced with a reference sample for measuring gloss to measure the gloss on the 100% base line and then, in place of the reference sample, a sample to be measured is set to measure the reflected light an 45 deg. in the incident and reflection angle. When measuring the gloss at 60 deg. in the incident and reflection angle, the flat mirror MR3 is replaced with the reference sample and the sample being measured, with the MR1 remaining intact.

Abstract: PURPOSE:To perform photometry with good reproducibility by using a commercial cylindrical test tube as a specimen cell and fixing the test tube by a holder consisting of an upright part and a stand of which the position is adjustable in an up-and-down direction while measuring absorbancy by an integrating sphere type photometric apparatus. CONSTITUTION:A test tube holder is constituted of an upright part 1 and a support stand 2 of which the position is adjustable in an up-and-down direction and V-shape grooves are formed to the upright part 1 and the support stand 2. A test tube T is placed on the groove of the support stand 2 to be contacted with the groove of the upright part 1 and pressed by the force of the spring 8 provided to a test tube presser 7. A light incident window 3 is provided to the upright part 1 and light is transmitted through the liquid of the test tube T from said window 3 and absorbancy is measured by an integrating sphere type photometric apparatus 1. Because the test tube is fixed by the test tube holder and absorbancy is measured by the integrating sphere type photometric apparatus, the absorbancy can be measured with good reproducibility by using an inexpensive commercial test tube.

Abstract: PURPOSE:To obtain a spectrophotometer with the minimized number of optical elements creating the shape of an optical path, by making it possible to load or unload required elements for measurement at a free position in a sample chamber with no fixed parts and constructions therein to facilitate the measurement of a sample in a desired large size according to the necessity.

To achieve this, the floor of the sample chamber 1 is made up of iron plate and a magnet attraction device is mounted on the undersurface of the integrating sphere 4. A sample 6 is held with a sample holder 8 which is screwed on a thread hole 10 on the top surface of a magnet stand 9. The magnet stand 9 can be lifted above the attraction surface by the operation of a lever 11 thereby holding even a sample of a substantial weight.

Abstract: PURPOSE:To obtain the transmissivety of the titled polarizing sample to natural light by making the projection light of a spectroscope incident on the polarizing sample through a linear polarizer, rotating the linear polarizer and polarizing sample by 90 deg. relatively, and averaging transmissivity values before and after the rotation. CONSTITUTION:The projection light of the spectroscope is made incident on the polarizing sample. The linear polarizer and polarizing sample are rotated relatively and an equation I is estimated from measure apparent transmissivity. An equation II is derived from the equation II. This equation II shows the relation between the apparent transmissivity and angular position of rotation of the polarizing sample on the optical axis of a spectrophotometer. When natural light is incident, light only in one polarization direction is reduced in energy to half and denoted as (a/2)+c. Therefore, the average of transmissivity gamma(theta+pi/2) at the time of 90 deg. rotation and transmissivity gamma(theta) at the time of 0 deg. is the transmissivity to the natural light.

Abstract: PURPOSE: To set both a measured and a contrast sample in contact with an integrating sphere, by providing the integrating sphere with two sample setting windows, causing luminous flux to strike one window at right angles and the other slantingly, nd replacing the measured sample and contrast sample at setting position with each other according to the kind of measurement.
CONSTITUTION: The output signal of a photodetector D is inputted to a sample holding circuits H1 and H2 through a preamplifier PA and sampling switches S1 and S2. The output signal of the sample holding circuit H1 is fed back to the photodetector D through a negative high-voltage circuit V and the sensitivity of the photodetector D is adjusted so that a contrast light measurement output is constant. The output signal of the sample holding circuit H2 is read in a computer CPU through an A/D converter by the measurement output of reflected light from the measured sample and further recorded on a recorder RD through a D/A converter. Thus, the contrast sample R and measured sample S are replaced with each other according to the kind of measurement, so which of two pieces f1 and f2 of luminous flux is used as contrast luminous flux is determined by switching.

Abstract: PURPOSE:To obtain a spectroscope capable of using in a wide wavelength range suppressing anomaly phenomena, by using a reflex diffraction grating in suitable wavelength before and behind in the range centering blaze reflection wavelength for heightening a utilization efficiency of light. CONSTITUTION:In a reflex diffraction grating, blaze reflection wavelength is determined by an angle of inclination beta of the saw-toothed step face at the time when a grating constant (d) is constant and in the case of Littrow's type constitution, the blaze reflection is brought about in the case when light is made incident vertically to the saw-toothed face. The grating having various blaze wavelength is made by varying the angle beta even if the constant (d) is the same and on the other hand, anomaly wavelength is determined by the constant (d) irrespective of the angle beta. The blaze wavelength is generated only one in one grating in the contrasting to the anomaly phenomena which are generated at three places in one grating and as occasion demands, the grating which is suppressed one or two anomaly phenomena being a hindrance to it are made in one or plural combinations.
