 +===== DOCCD instruments, techniques and cells =====
  
 +
 +=== Spectroscopic instruments and techniques ===
 +
 +  * Bruker 113v FTIR spectrometer, wavelength range 1 micron to 1 mm
 +  * Perkin Elmer Lambda 19 grating spectrometer, wavelength range 190 nm to 3200 nm
 +
 +
 +=== Systems and cells ===
 +
 +  * Specular-reflection and transmission sample holders for near-normal incidence
 +  * Liquid-helium cooled contact-gas cryostat CryoVac KONTI Spectro B
 +  * High-temperature high-pressure cell SPECAC P/N 585 0
 +  * Polarizers for UV to FIR wavelengths
 +
 +=== Calculation procedures ===
 +
 +  * Kramers-Kronig analysis to derive n and k from R (reflectance)
 +  * Lorentzian-oscillator fitting of R and T (thin films, Abelès formalism)
 +  * Reflection-corrected Beer-Lambert law in ranges of weak absorption
