Application Examples for Reflection Photometers


Our reflection photometers illuminate the probed material and measure the reflected signal at selected wavelengths. The reflectivity of the material at certain wavelengths depends on the concentration of its components, therefore the wavelength filters determine the measurement range and the accuracy of the detection and are selected according specifically for each application. Read more about the principle of operation on the page about the reflection photometer.

A special application is the measurement of the humidity and thickness of PVB interlayers in laminated safety glass for windshields.

The following table lists some of the measurement applications that we have been able to develop for our customers.
