The Bandpass Lens Filter 830 nm is engineered for near-infrared (NIR) imaging, transmitting light at its 830 nm peak wavelength while effectively blocking wavelengths outside the 7 80–880 nm spectral window. This selective NIR filtering enhances contrast, reduces visible-light interference, and improves imaging stability in demanding inspection environments. The filter mounts securely to standard machine vision lenses using the front filter thread, ensuring reliable mechanical and optical integration. With multiple thread sizes available, the BP830 fits a wide range of lenses and system configurations. Overview of the BP830 Narrow Bandpass Filter Narrow bandpass filters isolate a specific portion of the spectrum while rejecting all other wavelengths. The BP830 delivers: 90% transmission at the 830 nm peak 80% transmission throughout the 780–880 nm spectral window This passband corresponds to a 100 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.

For systems that require internal filter placement—such as lenses without a front filter thread—the BP830 can be mounted inside the C-mount interface between the camera and the lens. If you plan to install the filter inside the C-mount interface, simply fill out the form below to get instant access to the mounting guide and lens compatibility information. hbspt.forms.create({ portalId: "7372172", formId: "9b7a9007-56f1-47fe-8842-3e0b38317a2e", region: "eu1" }); Bandpass Lens Filter 830 nm: Near-Infrared Imaging Applications By isolating the 830 nm NIR band, the BP830 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 BP830 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 830 nm into Machine Vision Systems Most machine vision lenses include a front-mounted filter thread, allowing the BP830 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 BP830 easy to integrate into nearly any machine vision setup.
