Изобретение относитс к области спектра№ ного приборосгроетш и может найти применение при проведении спектрометрических изме . рений новышенноп точности.The invention relates to the field of spectral instrumentation and can be used when conducting spectrometric measurements. rhenium novyshennop accuracy.
Известны монохроматоры, содсржа1цие вход11ую и выходную щели, объективы и дисперnipyiouoje элементы-призмы или дифракционные решетки 11;Monochromators, input and output slits, lenses and dispersion prism elements or diffraction gratings 11 are known;
Недостатком этих приборов вл етс резко вьфаженна зависимость кривизны спектральных линий диспергирующих элементов от длины волны, что приводит к ухудшению разрешающей спрсобносш, снижению точности спектрометрических измерений и уменьшению светошлы монохроматоров.,The disadvantage of these devices is the sharply increased dependence of the curvature of the spectral lines of dispersing elements on the wavelength, which leads to a deterioration of the resolution of the distribution, a decrease in the accuracy of spectrometric measurements and a decrease in the light path of the monochromators.
Наиболее близким техническим решением вл етс монохроматор, содержащий входную и выходаую щели, объективы и диспергарующую систему, состо щую из призмы и дифракциовдой решетки 2..The closest technical solution is a monochromator containing an input and output slits, lenses and a dispersing system consisting of a prism and a diffraction grating 2.
Дл согласовани взаимного разворота призмы и решетки имеетс кинематический механизм .There is a kinematic mechanism for coordinating the mutual reversal of the prism and the grating.
При сложении дисперсий призмы и решетки кривизна их спектральных линий имеет прОтивопЬлршше знаки и взаимно компенси-. руетс .When adding the dispersions of the prism and the grating, the curvature of their spectral lines has the signs and is mutually compensated. Ruets
Недостатком этого монохроматора вл етс низка точность спектрометрических измерений, обусловленна оишбками сложного кинематического механизма соглатовани взаимного разворота при.змы и решетки.The disadvantage of this monochromator is the low accuracy of spectrometric measurements, due to the complexity of the complex kinematic mechanism for coordinating the mutual reversal of the prism and lattice.
Целью предлагаемого изобретени вл етс повышеш1е точности измерений.The aim of the invention is to improve measurement accuracy.
Цель достигаетс тем, что диспергирующа система вьшолнсна в виде призмы, на заднн о отражающую поверхность коТорс/t нанесены штрихи дифракционной решеткиThe goal is achieved by the fact that the dispersing system is executed in the form of a prism, and the grooves of the diffraction grating are applied to the back surface of the reflector surface.
Такое выполнение диспергирующей системы исключает механизм согласовани взаимного разворота призмы и решетки. Поскольку штрихи дифракщюнной решетки нанесены непосредственно на заднюю отражающую поверхность призмы. В св зи с отсутствием механизма согласовани устран ютс и оншбки, св занные с ним, что повьппает точность измерений и т1рощаетс сканирование спектра.This embodiment of the dispersing system eliminates the mechanism for coordinating the mutual reversal of the prism and the grid. Since the strokes of the diffraction grating are applied directly to the rear reflecting surface of the prism. Due to the lack of a matching mechanism, the onshbki associated with it are eliminated, which increases the measurement accuracy and simplifies scanning of the spectrum.
