#000026 Bi350 Near UV Interference Bandpass Filter

Bi350 UV narrowband interference filters can be used together with 350nm UV LED, UV fluorescent and other UV-producing lamp-based lighting. These can be found in any number of consumer, medical and scientific applications including insect attraction, pharmaceutical and other instrumentation. Bi350 filters are designed to efficiently block visible through near-IR wavelengths while passing UV light. They are also useful for near-UV fluorescence imaging, blocking visible light and light from deeper UV excitation sources. The substrate material is a precision polished absorptive filter glass that blocks deep red and near-IR wavelengths.
