Diffuse Reflectance Accessory (Internal)

Reflection consists of two components: specular and diffuse. Specular reflectance is the mirror-like reflection off a sample surface. Diffuse reflectance occurs when the surface reflects light in many different directions, giving the surface a matt appearance.

NIR Discussion Forum: ATR vs Diffuse Reflectance

Coupling the diffuse reflection measurement to the use of the near-infrared portion of the EM spectrum where the absorbtivity of most materials is small allows relatively deep penetration of almost any sample, when then automatically creates an effect of optically averaging the inhomogeneity of the samples.

Diffuse Reflectance Spectroscopy - an overview ...

Diffuse reflectance spectroscopy is a well-established technique for studying the spectral characteristics of opaque solid samples, based on the principle that not only does light reflected from the material come from the surface (specular reflection) but some is reflected internally (diffuse reflectance).

UV-vis Spectrometry - University of Cambridge

UV-vis Spectrometry. We use an Ocean Optics HR2000 spectrometer with a D 2 /halogen light source and reflection probe to to investigate the optical reflectance and absorbance of semiconductor photocatalysts, YBCO precursor sols and Cu-Ni alloys. The reflection probe measures the diffuse reflectance (light scattered to all angles) as a function of wavelength in a close approximation to the ...

What is the principle of diffuse reflectance spectroscopy ...

The difference in these techniques is that in UV/Vis spectroscopy one measures the relative change of transmittance of light as it passes through a solution, whereas in diffuse reflectance, one measures the relative change in the amount of reflected light off of a surface.

Diffuse reflectance infrared fourier transform ...

Diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) is an infrared spectroscopy technique used on powder samples with no preparation. The sample is added to a sample cup and the data is collected on the bulk sample. The infrared light on a sample is reflected and transmitted at different amounts depending on the bulk properties of the material.
