SphereSpectro 150H – A True Highlight in Spectrophotometry
Designed to handle all sample types - diffuse, scattering, and transparent.
Introduction to Spectrophotometry
In general spectrophotometry is a method to measure which substances absorb light by measuring the intensity of light as a beam of light passes through sample. The fundamental principle is that e
Limitations of Spectrophotometry
Sampling Time
Usually the spectral range starting in the UV 200 nm to NIR 2500 nm is of interest. Scanning devices based on double monochromators are often used. However, they have limitations due to rather long measurement times in the range of 10 minutes to 20 minutes depending on the wavelength range and sampling interval.
Turbid or Scattering Samples
Another limit are so called turbid or scattering samples. Since a part of the light is scattering and not absorbed additional to the spectral absorption coefficient also the spectral scattering coefficient is of interest. The design of a measurement setup that is able to measure both absolutely correct without any simplified modelling is non-trivial and the mathematical caculation algorithm is even more complex.
The Spectrophotometer Solution for all Samples
With the SphereSpectro 150 Series we have developed a spectrophotometer that can measure all samples precise and fast. Due to the use of array spectrometers measurement times of a few seconds (VIS and NIR) or in the range of a few minutes (full spectral range) are possible. Furthermore, a patented design and software algorithm allow the precise and accurate measurement of all samples.

Reflectance Standards
Diffuse reflectance calibration standards
Reflectance standards are diffuse reflectance calibration standards available in white or different grey levels. They provide traceable calibration for the wavelength range from 250 nm to 2450 nm. The standards are made of synthetic material and are available in white with 98% reflectance as well as in grey levels of 2%, 20%, 50%, and 70%.
