Optical Filters

About Tecnottica Consonni srl

• Type: Filters

Absorption filters are able to select particular bandwidths of the electromagnetic spectrum, excluding all those wavelengths outside of them. For this reason, there are absorption filters optimized for ultraviolet (UV), visible (VIS) and near-infrared (NIR and SWIR). In addition to absorption filters, Tecnottica produces and distributes dichroic interferential filters also known as dielectric layers filters: this category comprehends all the filters made of a glass substrate, usually borosilicate, on which are deposited metal films with infinitesimal thicknesses.
