for scattering samples from Berghof Gigahertz-Optik THIS BROCHURE GIVES AN OVERVIEW OF: Functionality, benefit and comparison to other analytical laboratory equipment on the market such as spectrophotometers.

What do typical spectrophotometers incorporating integrating spheres measure? What is different about the SphereSpectro 150H? Why can the SphereSpectro 150H deliver such high accuracy for these material parameters that others can’t? Why should the whole sample volume be taken into account and what is the resulting benefit? What type of samples can be measured? For what type of applications is it an advantage to measure both spectral absorption and spectral effective scattering coefficients? CASE STUDY: Measurement of chemical substances in quality control CASE STUDY: Reproducing the color...

In conventional spectrophotometer systems, the absorption coefficient is determined for clear samples (no scattering, just specular reflection and absorption) like colored glasses, etc. in order to perform these analytical investigations. The SphereSpectro 150H is a unique laboratory measurement system for simultaneously quantifying and discriminating two fundamental material properties of scattering media, namely the spectral absorption coefficient and the spectral effective scattering coefficient. Statement: “The determination of scattering and absorption coefficients is a challenge for...

What do typical spectrophotometers incorporating integrating spheres measure? What is different about the SphereSpectro 150H? In addition to the functions of conventional Spectrophotometer Systems, the SphereSpectro 150H offers the already briefly explained enhanced functionality based on the software algorithm. typical 8:d optical path through the sample determined by a comparison to a reference standard (relative measurement method) rentiation) is measured by typical 8:d reflection beams from the sample normalization beam transmission beam remission beam The hardware setup of the...

Why can the SphereSpectro 150H deliver this high accuracy for these material parameters which others can’t? Why should the whole sample volume be taken into account and what is the resulting benefit? Simply said, it´s because of the introduced model-based software algorithm. In the following picture the propagation of one ray is illustrated in the sample in order to get an appreciation of how the fundamental principle of the algorithm works. Typically, if you do conventional measurements with spectrophotometers (incl. integrating sphere) you perform transmission and reflection measurements...

For which type of applications are both - spectral absorption and spectral effective scattering coefficients – an advantage? For transparent samples such as water (with almost zero scattering ingredients) classical spectrophotometers are sufficient. Since the measurement performs remission and transmission measurements, the sample thickness must be appropriate in order that a transmission measurement is possible. The measurement system‘s software guides the user in optimizing this by analyzing the signal ratios. The sample should be homogeneous over the size of the detector port (25 mm...

CASE STUDY: MEASUREMENT OF CHEMICAL SUBSTANCES IN QUALITY CONTROL The SphereSpectro 150H can clearly distinguish between absorption and scattering inside of the sample and therefore makes it possible to take the measurement data of the spectral absorption coefficient to analyze the content of Paracetamol and Ibuprofen individually. A database of the pure content is needed and, based on superposition, the pure concentration of the substance is determined. Such types of measurement are of importance in production control. Color Measurement of Sample Material Color Measurement Software creates...

CASE STUDY: RENDERING The image compares two approaches: Rendered Image Real Image This is an example of how accurate the measurement results of the SphereSpectro 150H match the reality and hence it makes completely new applications possible. ●A picture taken with the camera ●A virtual picture calculated by com- puter (rendered picture) The lighting conditions are the same in both cases i.e. same position of light source relative to the plastic sample, same light spectrum and same intensity of light. The information on these lighting conditions are put into the rendering program on the PC....

Other advantages of the SphereSpectro 150H ● Easy sample handling. No need of complex sample preparation. Just fill the liquid samples into the cuvette or cut the solid sample to the needed geometry. Even some solid samples such as tablets could be processed into homogeneous powders and put into cuvettes. ● Measurement time is very short – within seconds ● Plug & Play with intuitive user software ● Large sample compartment with several probe fixing options ● Reduced maintenance costs What does SphereSpectro 150H stand for?
