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.

BP365 UV Blacklite dichroic filters can be used with all UV LED, UV fluorescent and other UV-producing lamp-based lighting. BP365 filter material is designed to block the visible and pass UV light and passes the 395nm wavelength and all other popular UV LED wavelengths. The substrate material is low-expansion Borofloat, making this filter highly heat resistant.

BP470 filters enhance viewing of subjects illuminated by blue LED lighting and any UV- excited blue fluorescence emissions (430-500nm). Its broad bandwidth and high peak (T >90%) transmission results in significantly brighter, higher contrast images. For most machine vision UV fluorescence applications, use of a BP470 filter is absolutely necessary.

BP505 are single substrate, hard-coated filters designed to match the output of most cyan LEDs. Coupled with the spectral sensitivity of most CCD/CMOS sensors in use today that also peak in this range, using this filter can result in images that are especially bright and very high in contrast. It is particularly useful for line scan/wide angle applications.

BP525 filter material is designed for use with green LED lighting, 532nm laser illumination and green UV fluorescence applications. A BP525 filter has a broader range, higher peak transmission and superior blocking of UV and NIR wavelengths compared to commonly found all-dichroic green bandpass filters improving contrast by blocking significantly more of the unwanted light.

Details
BP550 filters effectively pass all visible light and block all light outside the visible range without discoloring the image. This single substrate, hard-coated filter is designed for use in full color, white light applications where either IR or UV light (or both) may be present.

Details
BP590 filters are recommended for use in systems that make use of amber or orange LED lighting. These filters are also widely used in fluorescence imaging applications, particularly with dyes such as ethidium bromide, or when working with with Qdot 565, 585 or 605.

Details
A BP635 filter is recommended for use with 615-645nm LED and laser diode lighting. Because of its broad bandwidth and high peak transmission, BP635 filters work very well for all light red lighting applications in this range.
-
Details
A BP660 filter is recommended for use with 650-680nm LED and laser diode lighting. Because of the ample passband and excellent in-band transmission, it works well with all camera-related applications in this range.
-
Details
Recommended for use with near-infrared LEDs. BP695 is also useful for imaging typically weak luminescence where the subject is often excited with 635nm or 660nm red LED lighting.

Details
Recommended for use with near-infrared LEDs, BP735 filters are designed for viewing subjects in the 700-770nm range. Blocks all UV and visible light, optimizing results achieved with IR lighting used in traffic control and license plate recognition systems.
