Diffuse reflectance spectroscopy is extremely useful for analyzing rough surfaced samples and powders. However, it is difficult to analyze most of the rough surfaced samples with in-compartment ...

Using thin films of dielectric materials in optical coatings have long been common practice in the glass and optics industries. For example, Bragg mirrors in laser cavities are formed using ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

UV-visible-NIR microspectroscopic analysis of thin films on semiconductor wafers is one of the most common applications of the technique. In the UV-visible-NIR range, the interference spectra can be ...

The color mapping of in situ UV-vis reflectance spectra as a function of spin-coating time for PM6:Y6 blends with DIO (a) and with TCB (b). Normalized in situ absorption intensity at the wavelength of ...

The microseepage of gaseous hydrocarbons often creates a soil atmosphere containing lighter hydrocarbons (C1-C5). The gases in the soil may be sampled and analyzed to determine the specific mix of ...

Our Frontier FTIR allows spectroscopic investigations of the mid infra-red regions. Samples can be analysed using direct transmission - either as a raw material or in a KBr matrix - or via specular ...
