Bandpass Lens Filter 830 nm
- Select your size
- 830 nm peak wavelength
- useful range between 780-880nm
- useful range FWHM: 100 (±5 nm)
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 780–880 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.

Thread Size Options for BP830 Lens Filter
Because lenses come in different sizes, the BP830 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 BP830 with a C-mount (CMT) Filter Interface?
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.
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.
Performance Benefits of the 830 nm Narrow Bandpass Filter
Designed for precision near-infrared imaging, the BP830 provides highly selective wavelength transmission and consistent optical performance, making it suitable for demanding inspection and measurement tasks.
- • High transmission at the 830 nm center wavelength
• Strong blocking of visible and out-of-band NIR light
• Superior contrast enhancement in the 830 nm spectral region
• Stable optical behavior under variable illumination
• Reliable, repeatable performance for precision NIR imaging

The cameras are a great value for money and the lenses also. The software is outdated and needs refreshing. It took me considerable amount of time to discover how to access the camera features.

Recently we purchased a camera with lens, and LED lights. We are not experienced with machine vision but the installation worked out fine. After installation on our laboratory we were surprised again of the high quality of the photos and the versatility of this system. (options in Galaxy viewer and integration in Python. Recently we had an issue with the software and the customer support was able to give us the relevant information to fix it within one day. The next time we need a camera we will not be looking to other suppliers but contact GeT Cameras immediately.

For a new product development there was a lot of price pressure. We needed a cheap camera. I called them and Caspar was providing great support. He even advised a cheaper camera than I had in mind. I was just surprised by the inhouse knowledge of get cameras about machine vision. Never expected this from a webshop. The image an built quality of the camera is also great. The camera feels and operates the same as our Basler cameras.

In the beginning I was sceptic because of the low prices, but support by email was great. They advise a lens and provided additional technical information. Unfortunately they don't offer a loan service, but I decided to try it. I had the cameras in house within 2 weeks and connection was easy. The SDK looks like the SDK from Basler so I felt directly comfortable with it. The camera and lens was a perfect match and now I'm able to read small DMC codes on large products with just a single camera.
