Abstract: PURPOSE:To enhance an S/N ratio, by a method wherein rays of light having different wavelengths are guided to a reference specimen and a specimen to be measured and, thereafter, a pair of luminous fluxes of both specimens comprising same wavelength lights are again separated to be guided to different detector to obtain the permeability of the specimen to be measured and two-luminous- flux two-wavelength signals. CONSTITUTION:Rays of light from light sofurces 1, 2 for first and second wavelength lights are incident on a luminous flux splitting means 5 through first and second spectroscopes 3, 4 to be splitted while split rays are reorganized by a luminous flux reorganization means 8 through reference specimen and measuring specimen chambers 6, 7 while first and second wavelength luminous fluxes passed through reference and measuring specimen light paths R, S are allowed to be incident on first and second light detectors 9, 10. The signals of the detectors 9, 10 are allowed to be incident on a divider 20 through first and second dividers 11, 12 and the ratio of measuring and reference specimen light signals is calculated with respect to the first wavelength light by the first divider 1 and the same ratio is also calculated with respect to the second wavelength light by the divider 12 and the ratio of both of them is calculated by the divider 20.

Abstract: PURPOSE:To obtain an even base line by dividing luminous flux having different two wavelengths into four luminous flux of control light and sample light to introduce them to a control sample and a reference sample, and adopting the ratio of a signal ratio of the sample light to the control light in terms of one wavelength light to the ratio in terms of another wavelength light. CONSTITUTION:White light emitted from a light source 1 is diffracted to the light having different two wavelengths by spectroscopes 2, 3. Said light are introduced to the same position of two luminous flux dividing mechanism 4, divided respectively into two luminous flux, and said flux are absorbed by the control sample 5 and a sample 6 to be measured respectively and introduced to a detector 7. A signal discriminating circuit 8 discriminates signals S1 and R1 of the sample and reference light in terms of one wavelength light, and signals S2 and R2 of the sample and reference lights in terms of another wavelength light. These signals are subjected to calculation of (S1/R1)/(S2/R2) by a processor 9, and the result is displayed on a display device 10. In this way, the base line is evened and the light source brightness variation is corrected.

Abstract: PURPOSE:To make it possible to separate two wavelengths by one device, by using one common input slit for two diffraction gratings, which are independently rotated on the same axis, a collimator mirror, two telemeter mirrors corresponding to the two diffraction gratings, and two output slits. CONSTITUTION:Diffraction gratings G1 and G2 are independently rotated with a common axis X as a center. Light is inputted from an input slit S1. The light, which is inputted from the input slit S1, is made to be parallel flux by a collimator mirror M1. The light is inputted to the diffraction gratings G1 and G2. The light with one wavelength of the light inputted in the diffraction gratings G1 is reflected and diffracted and inputted to a telemeter mirror M2. The light is reflected by the M2, converged into an output slit S2, and inputted to a light detector PM1. The light with another wavelength of the light inputted to the diffraction grating G2 from the collimator mirror M1 is diffracted and inputted into a telemeter mirror M3. The light is reflected by the M3, converged into an output slit 3, and inputted to a light detector PM2.

Abstract: PURPOSE:To judge simply color rendering property of a high pressure sodium vapor lamp by obtaining the ratio of luminescence energies in two wave length areas of the light from a lamp. CONSTITUTION:The light from a sodium vapor lamp 9 is directed to a photoelectric transducer elements 3 and 4 through filters 1 and 2 which have a transmission band with wave lengths 590nm and 570nm with a half value width of 5nm as centers. The outputs I1 and I2 are inputted to a divider 5 to calculate I2/ I1. Its output I2/I1 is compared with a reference voltage V0 from a reference voltage generator 7 by means of a comparator 6. If it exceeds X0, a display element 8 is turned ON, and the color rendering property is easily judged.

Abstract: PURPOSE:To arrange detectors closely at a fixed distance to increase selectivity of an sample to be analysed by arranging the detectors on a spectrum image surface obtained by a spectral element to be dislo in the spectral directions in different degrees of spectra. CONSTITUTION:The solid-state image dectors 9lambda1, 9lambda2 are arranged so as to dislocate the wavelength dispersing directions within the photodetecting surfaces of positive primary spectrum S+1 and negative primary spectrum S-1 respectively. When wavelength lambda1 or lambda2 is to be changed, the detector 9lambda1 or 9lambda2 is dislocated in the wavelength dispersing direction within said respective spectra. Since two detectors are arranged so as to be displaced in the spectral directions within the different degrees of spectra on the spectrum image surface in this invention, the selectivity of an analying sample is extended independently of the interval between two wavelengths to be approached.

Abstract: PURPOSE:To fetch out alternately two wavelength light necessary for a two wavelength multi-item spectroscopic analyzing apparatus in a good SN ratio with a simple construction, by introducting the light from the spectrum face and using a spectroscope in an opposite direction. CONSTITUTION:Desired two wavelength light is outputted alternatively and selectively by a wavelength selective plate 11 provided on the spectrum face of a spectroscope and an image is formed on a SELFOC lens or an optical fiber 13 being situated in a conjugate position to the plate 11 through a camera mirror 8, a grating 10, a collimator mirror 9 and a slit 12 and then, said image is made incident to a flow cell 14 of every analyzing item. The desired two wavelength light necessary for two wavelength multi-item spectroscopic analysis is fetched out alternately in a good S/N ratio by a simple construction eliminating the need for a respective optical element such as interference filters etc. of this wavelength light.

Abstract: PURPOSE:To improve precision by eliminating the effect of temperature fluctuations of interference filters upon a measurement result, by irradiating all interference filters with light from a light source all the time and by guiding light passed through a specific filter to a sample. CONSTITUTION:Light guides 22 are provided as many as interference filters 24, which are irradiated with light from a light source 21 all the time. A rotary member 25 is turned under an interference filter holding member 23 fixed in position to guide light passed through a prescribed interference filter 24 to a prism 29 through a light guide 28, and the luminous flux is changed in direction to a prescribed phodometric position to irradiate a reaction pipe 35, containing a sample liquid 34, with the luminous flux; and the light passed through the reaction pipe 35 is photodetected by a photodetector 36 and converted photoelectrically to measure the light absorbance of the sample liquid 34. Each interference filter 24 never changes in characteristics at the beginning of photometric operation, so accurate data is obtained.
