Abstract: PURPOSE:To eliminate the spatial restriction of a measuring sample during the measurement of reflectance without significant alteration of two luminous flux formation systems, by positioning the measuring sample behind a reference sample in the incident direction of a luminous flux in such a manner as not to contact the reference sample. CONSTITUTION:In a double-beam type ultraviolet, visible light spectrophotometer or the like a reflector M1 reflects a luminous flux R on the side of a reference optical path so as to be incident on a reference sample MR at a specified angle of incidence. A reflector M2 reflects the luminous flux reflected from the sample MR so as to be incident on a detector along the extension of the luminous flux R incident on the reflector M1. A reflector M3 reflects a luminous flux S on the side of the optical path of the sample so as to be incident on a measuring sample MS at a specified angle of incidence the same as that of the luminous flux R into the sample MR. A reflector M4 reflects the luminous flux reflected from the sample MS so as to be incident on the detector along the extension of the luminous flux S incident on the reflector M3. Then, the interval between the reflectors M3 and M4 is made so larger than the interval between the reflectors M1 and M2 as to place the sample MS behind the sample MR thereby making the angle of incidence on the sample in the manner that both of the optical paths are equal to each other.

Abstract: PURPOSE:To exclude the cause of errors, by arranging a singe window having no corresponding window on any opposed wall surface on an integrating sphere and a pair of windows corresponding to each other with the center of the sphere therebetween to make the positional relationship between the incident luminous flux and the integrating sphere rotatable to enable one integrating sphere to cover the measurement of transmission light and reflected light. CONSTITUTION:In the measuring of transmission light, as shown by the drawing A, the positional relationship between an integrating sphere I and incident luminous flux S is such that the luminous flux S is incident through a single window Ws having no window on any opposed wall surface of the integrating sphere and a sample L is placed in front of the single window Ws. As the internal surface of the integrating sphere is opposite the single window Ws, the condition in the internal reflection of a sample light incident into the integrating sphere is the same whether measurement is done at the transmittance of 100% or with the sample placed diffusing luminous flux as illustrated, thereby eliminating any cause of errors. In the measuring of the reflected light, luminous flux S is made incident through a window Wr as illustrated by B and a reflection reference plate RS and a sample D are set alternately in contact with the outside of the opposed window Wb.

Abstract: PURPOSE:To enable highly accurate measurement with a simple construction, by providing an integrating sphere with a light incident window, a detection window and additional one window the same in the area as the light emission window. CONSTITUTION:A light source unit L, a spectrometer M and an integrating sphere S are arranged. The integrating sphere S is provided with a light incident window W1, a detector window D, a photo detector P and a window W2 the same in the area as the window W1. A sample G shall be a plate of optical glass. To measure the transmittance 100%, the sample G is set at the position as indicated by the chain line and the window W2 is closed while the window W1 opened. In the measurement of the sample, the sample G is set at the position of the solid line and the window W2 is opened. In such a manner, a highly accurate measurement can be done with a simple construction simply by providing additional one window W2 on the integrating sphere S.

Abstract: PURPOSE:To eliminate the influence of the movement of a measuring luminous flux by a sample and to improve quality control by constituting a spectrophotometer in such a manner that an integrating sphere is disposed in the light inlet side of a spectroscope and that the light transmitted through the sample is made incident on the spectroscope through the integrating sphere. CONSTITUTION:The integrating sphere IS is disposed on the light inlet side of the spectroscope M. The spectrophotometer is so constituted that the light transmitted through the sample is made incident through the sphere IS on the spectroscope M. More specifically, a light incident window W1 is opened toward a measuring optical system L in a preliminarily placed optical system P and the image of a light exit window W2 is formed by a lens l5 and a mirror ml onto the inlet slit S1 of the spectroscope M. The integrating sphere is used as the preliminarily placed optical system of the spectroscope in the above- mentioned manner and therefore there is no influence of the movement of the measuring luminous flux by the sample and the direct measurement of the product such as worked part on the production site of a factory, etc. is made possible. The quality control is thus improved.

Abstract: PURPOSE:To enable measurement of color with sufficient sensitivity by lighting with a commercial power source by a constitution wherein a fluorescent discharge lamp is used as a power source of white light and reflected light is interrupted intermittently by a frequency which is the same with the frequency of the lighting voltage of the lamp or is the frequency multipled or divided by integral numbers thereof. CONSTITUTION:In the device wherein white light is applied to a color sample S to be measured and a control sample R and respective reflected light thereof is measured through spectral diffraction, the fluorescent discharge lamp is used as a power source 1, while a sector 5 making the light flux of the reflected light from the samples S and R by interrupted intermittently and fall on a spectroscope 6 is rotated, by a synchronous motor 7, with the frequency which is the same with the lighting frequency or with the frequency multipled or divided by the integral numbers thereof, and thus photoelectric current (i) corresponding to the strength of diffracted spectrum is detected. By this method, the surfaces of the samples can be irradiated directly by the face light source of the fluorescent lamp without using an expensive integrating sphere and thereby high sensitivity can be obtained.
