Methods and areas of application

ASO Magnifier

Color measurement

A color measurement can be carried out using colorimeters or spectrophotometers under various standardized lighting or detector geometries. One obtains either color values in the CIE Lab color space or spectral curves.

application areas

  • Quality control

  • Quantification of color deviations

  • Metamerism

  • Colour constancy checks after environmental simulation tests

ASO Magnifier

Gloss measurement

Gloss measurement determines the directional portion of the reflection of a surface. Various standardized measuring geometries are available for the measurement

(20°, 60° and 90°). The reflectometer value is related to a standard (black polished glass plate).

application areas

  • Quality control

  • Determination of the degree of gloss or gloss deviations after durability tests

ASO Magnifier

Light
microscopy

Light microscopy enables the optical examination of small structures.

field of use

  • Damage analysis

ASO Magnifier

Laser particle size measurement

Particles in a suspension scatter the laser light. The size distribution can be calculated based on the intensity distribution in the diffraction pattern.

application areas

  • Quality control

  • Particle size distribution

  • Droplet size in emulsions

ASO Magnifier

UV-Vis spectroscopy

In molecular spectroscopy, the incoming light is absorbed or scattered. This is characteristic of certain molecular fragments. The recorded spectra show specific bands for certain molecular components, which can be used to identify organic materials in particular.

application areas

  • Analysis of organic components

  • Polymer characterization

  • Damage analysis

  • Stains and dirt

  • Analysis of competitive products
