Colour filters

We produce about 50 different standard colours, or set your desired colour.

The colour is independent of the thickness. This means that you can use a certain colour reference in e.g. 0.8 mm together with a 1.5 mm glass. Or that your product will not look different if you change the thickness of the glass. Besides the standard colours, we can also reproduce custom colours. Just ask us! As standard, our glasses are equipped with a UV absorber. However, we also supply UV-transparent versions, or on the contrary with double UV protection, e.g. for the protection of works of art, or historical documents. Or VIS filters that shield IR sensors from visible light.
