  1. 1. Development of prototype of Fourier Transform spectrophotometer for UV-Vis-NIR range 2013
  2. 2. Project aimDevelop fast compact high-presicion Fourier Transform spectrometerwith working range from ultraviolet through visible to infraredwavelengths Featuring • Spectral resolution 5 cm-1 constant in working range (wavelength resolution of 0.05 nm in UV range) • Active anti-vibration system • Automatic calibration • Compact design for daily lab use • Compatible with standard spectroscopy accessories • Modern software package with user-friendly interface
  3. 3. Project Status• Complex problem of application of Fourier Transform method to UV-Vis spectrophotometer has been solved• We have developed experimental prototype Fourier Transform spectrophotometer for UV-Vis-NIR rangeFirst in the world desktop Fourier Transform spectrophotometerfor UV-Vis-NIR range Key characteristics:  Working wavelengths range from 300 to 2500 nm  Spectral resolution 10 cm-1  Signal to noise ratio 100 dB  Spectrum registration speed – 40 spectra per second  Key FTS element – Michelson interferometer with single moving mirror
  4. 4. Distinctive featuresIn our FT UV-Vis-IR spectrometer, we have successfullyapplied new building approach instead of the classic principlethat is widely used in FT IR spectrometers:• High signal-to-noise ratio• Large aperture and high light throughput• High accuracy of wavenumbers determination• High frequency resolution constant along the working spectral range• Wide working spectral range• Absence of errors caused by diffusive and diffractive elements• Fast speed
  5. 5. Solved problem description All the UV-Vis spectrophotometers on the market are based on dispersive method of operationExisting FT spectrometers are used only in NIR and IR spectral ranges Drawbacks of Advantages of FT spectrometers: dispersive 1. High signal-to-noise ratio (Fellgett’s advantage or multiplex spectrometers: factor)  Small aperture (low 2. Large aperture and high light throughput (Jacquinots advantage). light) 3. High accuracy of wavenumbers determination (Single  Slow speed wavelength, e.g., laser line, is enough to calibrate the device in the  Large errors and entire working spectral range) limited dynamic range 4. High frequency resolution constant along the working spectral due to diffusion on the range diffractive grating 5. Wide working spectral range  Complex design 6. Absence of errors caused by diffusive and diffractive elements  Errors caused by higher orders of 7. Fast speed (by 100-1000 times faster than dispersive diffraction spectrometers based on scanning monochromator). In this project for the first time in the world we shall develop compact FT spectrophotometer for UV-Vis-NIR spectral range
