RESEARCH PRODUCT

Advanced Hardware and Software for the Upgrade of Mirror/Prisma Monochromator SPM-2 (Carl Zeiss Jena) for the Measurements of Basic Spectroscopic Properties of Atoms in Near VUV, Far UV, UV Spectral Region

subject

description

Today's digital electronics and fast computers allow the efficiently processing of large volumes of spectroscopic information, which means the opportunity to reuse and upgrade monochromator with sophisticated optical and mechanical systems being designed and used in the middle of the last century. Particular interest is towards high-resolution prism monochromator. We used such an approach to computerize manual operations of universal mirror monochromator SPM-2, which has changeable quartz, glass, NaCl and KBr crystal prisms. SPM-2 was produced by VEB Carl Zeiss JENA in the early sixties of the last century (in former GDR), and its advanced features were widely used [1]. The current interest is to use upgraded double pass SPM-2 (with quartz prisma) for atomic spectroscopy measurements in broad intensity range in near VUV, far UV, UV. Alongside standard measurements, cooled photomultipliers, photon counting mode can be used to ensure the fixing of very weak spectroscopic lines. We are using the instrument to investigate resonance spectra of atomic iodine, bromine, arsenic, selenium, tellurium, boron. Particularly duplet of atomic boron resonance lines 249.6769/249.7722 nm is easily resoluble. The approach has a high value for money because of the absence of handy monochromators for high-resolution atomic spectroscopy in the identified spectral region on the market.
