Spectrophotometry

Spectral measurements

We offer reliable spectral measurement services, and accurate color-measurements of solid and liquid samples. We can measure optical reflection, transmission and absorption properties of samples with high precision in the ultraviolet, visible and infrared wavelength ranges. We can also perform spectral fluorescence measurements (ultraviolet and visible light).

An expert from the Computational Spectral Imaging group will perform all the measurements for you.

We can measure 3 samples/hour (using full wavelength range). All measurements are done optically, so the measurements will not damage the samples. Typical sample size is few cm².

The data gained from the measurements can be used, e.g., for designing light sources and optical filters, for optimal detection of objects-of-interest in machine vision applications, for determining products’ optical reflection and transmission properties in various wavelength regions, for designing product’s color appearance for various observers under different illuminations, and for designing the fluorescence-properties of products.

• PerkinElmer Lambda 1050 spectrophotometer (spectral reflectance, transmittance, and absorbance measurements; 175 – 2500 nm)
• PerkinElmer FL-8500 spectrofluorometer (spectral fluorescence measurements; 200 – 900 nm)

In our services, we follow the official price lists of the University of Eastern Finland which are checked annually.
