摘要： A COMBINATION TEACHING AID AND MODULAR INSTRUMENTAL ANALYSIS SYSTEM IN WHICH A PLURALITY OF MODULES ARE PROVIDED, EACH HAVING A SEPARATE FUNCTION, AND IN WHICH THE DIFFERENT MODULES ARE ADAPTED TO BE PLACED TOGETHER IN DIFFERENT COMBINATIONS TO PROVIDE DIFFERENT OPTICAL ANALYSIS INSTRUMENTS. THE MODULES INCLUDE A LIGHT SOURCE FOR PROVIDING LIGHT, A DETECTOR MODULE FOR RECEIVING LIGHT WHICH HAS BEEN EXPOSED TO A SAMPLE COMPARTMENT MODULE WHICH RECEIVES ONE OR MORE SAMPLES TO BE ANALYZED, AND MANY INCLUDE DISPLAY MEANS IN THE FORM OF A METER OR THE LIKE FOR READING THE OUTPUT OF THE DETECTOR MODULE. THE COMBINATION MAY ALSO INCLUDE A MONOCHROMATOR UNIT FOR PROVIDING SUBSTANTIALLY MONOCHROMATIC LIGHT, AND A FILTER MODULE WHICH IS ADAPTED TO CONTAIN ONE OR MORE FILTERS THROUGH WHICH A LIGHT BEAM MAY BE PASSED FOR OBTAINING A BEAM OF DESIRED FREQUENCY. DIFFERENT ARRANGEMENTS OF THE VARIOUS MODULES WILL PRODUCE A SPECTROPHOTOMETER, A FILTER PHOTOMETER, OR A NEPHELOMETER. THE DESCRIBED MODULE UNITS ARE ARRANGED SO THAT AT LEAST SOME OF THEM MAY BE DISPOSED ON A BASE AND OPTICALLY ALIGNED BY MEANS OF COMBINATION ADJUSTING AND CLAMPING MEANS, SO THAT THE UNITS MAY BE THEREAFTER MOVED, OR REPLACED AS DESIRED WITHOUT AFFECTING THE ALIGNMENT THEREOF. THE DESCRIBED UNITS ARE CONSTRUCTED AND ARRANGED SO THAT ALL THE SIGNIFICANT OPERATIONAL AND FUNCTIONAL PROPERTIES OF EACH MODULE MAY DE DIRECTLY OBSERVED BY THE STUDENT. THEREFORE, EACH MODULE IS ADAPTED TO PERFORM A MINIMUM NUMBER OF FUNCTIONS, AND THE MODULAR CONCEPT AND THE CONSTRUCTION FEATURES ARE USED AS A TEACHING AID USED TO EMPHASIZE THE RELATION BETWEEN VARIOUS SYSTEMS OF OPTICAL INSTRUMENTAL ANALYSIS. THE FILTER COMPARTMENT MODULE AND THE SAMPLE COMPARTMENT MODULE INCLUDE HOLDER MEANS FOR HOLDING LIGHT FILTERS OR SAMPLE UNITS, AND THE HOLDER MEANS FOR HOLDING LIGHT SO AS TO FACILITATE INTERCHANGE OF THE SAMPLE HOLDERS AND FILTER UNITS, AND TO BE ADAPTED FOR USE WITHOUT CHANGE TO PERFORM DIFFERENT FUNCTIONS IN DIFFERENT INSTRUMENTAL COMBINATIONS.

摘要： The advantage of sustained wavelength accuracy and mechanical simplicity of a spectrophotometer using a photodiode array as photometric detector and a fixed diffraction grating as dispersion means may be limited to a relatively short wavelength range by problems of stray light, second order errors and overloading of the detector at portions of the wavelength range. By utilizing repeat scanning of the array, each scan being modified by using a different source lamp and correction filters, freedom from the cited problems over part of each scanned wavelength range can be effected. A computer controls the scan sequence and combines the usable portion of each scan to produce error free operation over an extended range.

摘要： This invention is directed to a digital wavelength calibration system for a spectrophotometer, which includes a photodiode array that forms an output detector for the spectrophotometer, a light source for generating at least one reference emission line of known peak wavelength, a computer controlled mechanism for causing the peak of said reference line to fall in close proximity to the center of a preselected pixel of said photodiode array, peak location computing apparatus for computing the exact position data of the peak relative to the pixel center in terms of the pixel spacing and the ordinal number of the preselected pixel and for retaining this position data for subsequent wavelength computation, wavelength identification computing apparatus for computing the numerical relationship data of the ordinate number of each pixel to the wavelength falling on that pixel and for retaining this relationship data for subsequent correlation with data generated by the pixel, and apparatus for computational processing and display of the data correlated with the associated wavelength value.
