Instructional spectrometer

Claim 1

AN EDUCATIONAL SPECTROMETER FOR PERFORMING EXPERIMENTS AND MAKING MEASUREMENTS UTILIZING THE PRINCIPLES OF OPTICS, ELECTRONICS AND RADIATION PHYSICS COMPRISING, IN COMBINATION, (A) A BLACKENED FLAT BASE HAVING A TOP LAYER OF FERROMAGNETIC MATERIAL ON WHICH ELEMENTS MAY BE MECHANICALLY AND MAGNETICALLY POSITIONED, (B) A LIGHT SOURCE ASSEMBLY INCLUDING A BRACKET WITH AN APERTURE REMOVABLY MOUNTED TO SAID BASE, A CHOPPER ASSEMBLY SLIDABLY MOUNTED TO SAID BRACKET SUCH THAT THE CHOPPER ALTERNATELY BLOCKS AND PASSES RADIATION THROUGH SAID APERTURE, AND AN ENCASED LIGHT SOURCE WHICH IS SLIDABLY MOUNTED ON SAID BRACKET TO ALIGN SAID SOURCE WITH SAID APERTURE AND HAVING AN INCLINED FRONT SURFACE WITH AN OPENING THEREIN WHICH IS IN ALIGNMENT WITH SAID APERTURE WHEN POSITIONED ON SAID BRACKET AND WHICH TERMINATES IN A SHELF ADAPTED TO HOLD SAMPLES ON SAID SHELF OVER SAID OPENING, (C) COLLIMATING AND FOCUSING OPTICAL MEANS MOVABLY MOUNTED ON SAID BASE, (D) A MOVABLE MOUNTING BRACKET HAVING A POINTER ON ONE EXTREMITY THEREOF WHICH IS POSITIONED ON SAID BASE BY MEANS OF A PIN AND IS PREVENTED FROM FREELY ROTATING ABOUT SAID PIN BY A PERMANENT MAGNET MOUNTED THEREON, SAID BRACKET HAVING A HOLDER ON ITS OTHER EXTREMITY WHICH IS CAPABLE OF HOLDING AND AND ALIGNING EACH OF A PLURALITY OF DIFFERENT OPTICAL DISPERSION ELEMENTS, (E) A RADIATION DETECTOR ASSEMBLY INCLUDING A HOLDER MOUNTED MAGNETICALLY TO SAID BASE, SAID HOLDER HAVING A RADIATION DETECTOR REMOVABLY MOUNTED THEREIN, (F) SAID LIGHT, COLLIMATING AND FOCUSING OPTICAL MEANS, OPTICAL DISPERSION ELEMENT, AND DETECTOR BEING IN OPTICAL ALIGNMENT ON SAID BASE WHEREBY VARIOUS RADIOMETRIC AND SPECTRAL EXPERIMENTS MAY BE MADE, AND (G) A PLURALITY OF MOVABLE STRAY LIGHT BAFFLES MOUNTED MAGNETICALLY ON SAID BASE AND POSITIONED BETWEEN THE VARIOUS COMPONENTS TO PREVENT INTERFERENCE THEREBETWEEN.
