What is the NBP450-20nm Narrow Bandpass Filter?
The NBP450-20nm is a narrow bandpass filter with a central wavelength (CWL) of 450 nm and a bandwidth of 20 nm (FWHM). Because the filter has a relatively narrow bandwidth, it suits applications that require a purer band of blue light.
Where are 450nm Narrow Bandpass Filters typically used?
The NBP450-20nm Narrow Bandpass Filter mainly serves applications that require precise extraction of weak blue light signals from complex light environments. These applications include but are not limited to fluorescence microscopes, PCR instruments, 3D sensors, color sorting machines, spectrophotometers, and water quality analyzers.
