Abstract

Spektrometar sa CCD detektorom kompaktna je varijanta spektrometra s difrakcijskom rešetkom, bez pomičnih dijelova koje inače sadrži svaki „klasični“ spektrometar. U ovom spektrometru difrakcijska je rešetka nepomična, a spektar se registrira na CCD detektoru linearnog tipa. U prvom dijelu rada bit će objašnjena teorijska podloga spektrografije. Nakon toga bit će objašnjen princip rada jednostavnih spektrografskih ureĎaja, uz odvojeni osvrt na različite tipove detektora. Na primjeru će biti prikazano kako radi USB spektrometar te će se njime istražiti neki tipični spektri. U posljednjem, metodičkom dijelu rada, bit će istražena mogućnost konstrukcije jednostavnog priručnog spektrometra. Uz vrlo nisku cijenu kombiniranu s jednostavnom izradom, ovakav spektrometar moguće je lako konstruirati te primijeniti u školskoj nastavi.

Abstract (english)

Spectrometer with a CCD detector is a compact version of a diffraction grating spectrometer, without any movable parts that can normally be found in a „classic“ spectrometer. In this spectrometer, the diffraction grating is non-movable, and the spectrum is measured on a linear CCD detector. In the first part of this thesis we will explain the basic theoretical background of spectrography. After that we will explain the basic operation of typical spectrographic devices, with a separate part dedicated to different types of detectors. We will also show how a USB spectrometer is operated and explore the spectra of some typical sources. In the last, educational part of this thesis, we will consider the possibility of constructing a simple hand-held spectrometer. With an extremely low price combined with a simple construction, this type of spectrometer could easily be assembled and used in schools.
