Bandpass Lens Filter 880 nm, Select your size, 880 nm peak wavelength, useful range between 850-910 nm, useful range FWHM: 60 (±5 nm)

The Bandpass Lens Filter 880 nm is optimized for near-infrared (NIR) imaging, transmitting light at the 880 nm peak wavelength while blocking wavelengths outside the 850–910 nm useful range. This precise spectral control improves contrast, reduces visible-light interference, and ensures stable performance in demanding inspection, sensing, and machine-vision environments.

The filter mounts directly to standard machine vision lenses using the front filter thread. With multiple thread-size options available, the BP880 integrates seamlessly with a wide range of industrial optics.

How the BP880 Narrow Bandpass Filter Works

Narrow bandpass filters isolate a specific portion of the spectrum while rejecting all other wavelengths.  The BP880 delivers:  

• 90% transmission at the 880 nm peak  
• 80% transmission throughout the 850–910 nm spectral window  

This passband corresponds to a 60 nm FWHM (±5 nm), offering a broad and efficient NIR range ideal for high-intensity illumination systems and applications requiring strong NIR throughput and deeper material penetration.

Thread Size Options for BP880 Lens Filter

Because lenses come in different sizes, the BP880 filter is available in several standard thread options, making it suitable for both compact and larger lenses.

• C-mount filter

• 0.5 thread (pitch): M22.5×0.5, M25.5×0.5, M27×0.5, M30.5×0.5, M34×0.5, M35.5×0.5, M37×0.5, M37.5×0.5, M40.5×0.5

• 0.75 thread (pitch): M37×0.75, M43×0.75, M46×0.75, M49×0.75, M52×0.75, M55×0.75, M58×0.75, M60×0.75, M62×0.75, M67×0.75, M72×0.75

Want to use BP880 with a C-mount (CMT) Filter Interface?

For systems that require internal filter placement—such as lenses without a front filter thread—the BP880 can be mounted inside the C-mount interface between the camera and the lens.

Bandpass Lens Filter 880 nm: Near-Infrared Imaging Applications

By isolating the 880 nm NIR band, the BP880 improves clarity, minimizes visible-light interference, and supports higher-precision feature analysis across a range of imaging environments.

This makes it ideal for systems that rely on near-infrared illumination to highlight details that conventional lighting cannot reveal.

Key advantages with monochrome cameras:

- Reveals features hidden under visible light

- Boosts detection of faint or low-contrast textures

- Performs well in outdoor or fluctuating lighting

- Suppresses ambient visible-light contamination

Benefits when used with broadband sources:

- Stronger contrast across the NIR spectrum

- Better differentiation of subtle material variations

- Improved imaging consistency

- Reduced reflections from glossy or metallic surfaces

With these benefits, the BP880 is a powerful tool for industrial inspection, biometric identification, laser-illumination systems, material classification, and other NIR-enhanced machine-vision applications.

Mounting Bandpass Lens Filter 880 nm into Machine Vision Systems

Most machine vision lenses include a front-mounted filter thread, allowing the BP880 filter to be attached directly.

If you are using a C-mount lens on a GigE camera or USB3 camera, the filter can also be placed inside the C-mount connection instead of on the front of the lens.

Installed between the camera and the lens, the filter remains fixed within the optical path, ensuring stable alignment and consistent image performance.

These versatile mounting options make the BP880 easy to integrate into nearly any machine vision setup.

Performance Benefits of the 880 nm Narrow Bandpass Filter

Designed for precision near-infrared imaging, the BP880 provides highly selective wavelength transmission and consistent optical performance, making it suitable for demanding inspection and measurement tasks.

• • High transmission at the 880 nm center wavelength
  • Strong blocking of visible and out-of-band NIR light
  • Superior contrast enhancement in the 880 nm spectral region
  • Stable optical behavior under variable illumination
  • Reliable, repeatable performance for precision NIR imaging
