Applications

Both UV bandpass filter are suitable for the water purification with appropriate UV sources which have a strong emission in the region of about 340 (365) nm, but also for other UV applications in industry where a desired UV radiation in the region of 340 nm (365) nm shall be efficiently separated from disturbing radiation in wavelength regions in the VIS and IR.
