Multiband pass filters can be designed with up to ten bandpass ranges according to customer requirements. This allows for simultaneous observation of several wavelength ranges with a single filter optic - for example in fluorescence applications.

Among other things, these optical filters are characterized by high blockings between the passbands. They achieve typical optical densities >OD 8 by Design and at the same time offer a high transmittance of up to >98% as well as steep slopes.
