The molar extinction coefficient of Hb has its highest absorption peak at 420 nm and a second peak at 580 nm. Its spectrum then gradually decreases as light wavelength increases. On the other hand, H b O 2 {\displaystyle HbO2} shows its highest absorption peak at 410 nm, and two secondary peaks at 550 nm and 600 nm.
The light source consists of a Xenon flash lamp for the ultraviolet (UV) as well as for the visible (VIS) and near-infrared wavelength regions covering a spectral range from 190 up to 1100 nm. The lamp flashes are focused on a glass fiber which drives the beam of light onto a cuvette containing the sample solution.

By measuring near-normal incident reflectance (R) of the film (from 190 to 1000 nm), and analyzing R using the Forouhi–Bloomer dispersion equations, the film can be completely characterized. The Forouhi–Bloomer dispersion equations in combination with Rigorous Coupled-Wave Analysis (RCWA) have also been used to obtain detailed profile ...
