BP324 Near-UV Bandpass Filter
Near-UV Bandpass Filter for machine-vision imaging — passes 290-365nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
Useful in UV imaging applications, BP324 filters have a broad spectral bandwidth in the UV while effectively blocking most visible and infrared light. Note that there is a slight deep red/near IR leak that peaks at about 720nm. Because this filter absorbs all unwanted visible and/or infrared light, it is not recommended for placement in front of intense (white) light sources. • Passes UV portions 320-380 nm and 280-320nm
• Blocks < 280 nm
• Configurations can also be supplied for mounting in front of UV LED light sources
