ITAS-01 imaging time-analyzing spectrograph

The spectrograph is intended for application in non-stationary spectroscopy and permit to record a spectra dynamics of high-speed processes occurred in visible and NIR spectral ranges in single-frame and streak modes of recording. It is based on imaging monochromator-spectrograph of MS3504i-type (produced by joint Belorussian-Japanese enterprise «SOLAR TII») coupled with a streak camera K008 of our own production.

Article s [38, 43] in "Publications" section are devoted to designing and tests of this spectrograph.

Possible fields of application:
  • laser physics,
  • non-linear optics,
  • non-stationary spectroscopy,
  • ecology (register in the lidar-type systems of  detection and determination of location, dimensions and chemical composition of water or air pollution), etc.

Main components of the camera:

The devise consists of two main parts - the monochromator proper- spectrograph of MS3504i-type, which disintegrates registered process radiation into a spectrum with astigmatism correction and K008 streak and single-frame camera , whichprovides temporal analysis of this spectrum in a single-frame mode of record or in streak mode.
K008 streak camera is a multichannel detector that amplify image brightness up to not less then 5×10 3 times at the maximum of spectral sensitivity of the streak tube. Thus ITAS-01 has a hundred times more and tens thousand times more number of registered channels in streak and single-frame modes respectively than a similar spectrograph coupled with a photomultiplier (PMT), which is a single-channel spectrograph.
