Key Features of the SphereSpectro 150H
Measurement Principle and Applications
The SphereSpectro 150H employs a fundamental principle allowing the determination of both the spectral absorption coefficient and the spectral effective scattering coefficient, essential for analyzing diffuse scattering samples’ physical and chemical properties. Unlike traditional spectrophotometers that focus solely on absorption or transmission, the SphereSpectro 150H provides comprehensive analysis, making it indispensable for applications requiring absolute measurements.

For instance, the device can be used to evaluate the aging behavior of metalworking fluids by simultaneously determining droplet size, pH value, and concentration. It also aids in process control by measuring effective scattering coefficients to determine the fat content in homogenized milk through multivariate data modeling.

Ease of Sample Preparation
The SphereSpectro 150H simplifies sample preparation compared to traditional spectrophotometers. Solid translucent samples are easily held using the sample holder, while liquid samples can be conveniently filled into cuvettes provided with the system, eliminating the need for special pre-treatment.

Optical Property Determination with an Integrating Sphere
An integrating sphere is used to measure the total reflection and transmission of scattering samples, integrating radiation over the entire sample surface. By comparing these measurements with theoretical models, the spectral absorption and scattering coefficients can be determined. The software provided with the SphereSpectro 150H includes a robust algorithm for precise simulation of light propagation within the integrating sphere. Users can input parameters such as sample thickness and refractive index, and the automated evaluation process takes seconds to minutes.
