Bandwidth Interference- Bi Series

MidOpt Bandpass Filters are specially designed for industrial imaging


Bi Series - Narrow Bandwidth Interference


Bandpass Filters are used in a variety of industries, including machine vision,factory automation, security and surveillance, license plate recognition, medical and life science, agricultural inspection, aerial imaging, motion analysis, photography and cinematography.

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.

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.
