In the case that the properties of a particular filter are not known, we can use a spectrometer to perform an accurate analysis. We also use this equipment to determine the transmission of grey filters and thereby calculate the required thickness for your given application.

Depending on the requirements we use a Perkin Elmer spectrometer equipped with a grid monochromator or a diode array spectrometer. We are able to issue a test report on request.
