NBP635 narrowband filter is a narrowband filter designed for 635nm wavelength and is widely used in laser ranging systems. This filter can effectively isolate non-target band light, allowing only a narrow band near 635nm to pass through, shielding unnecessary spectral components, ensuring that the system receives mainly the echo signal of the target laser, thereby significantly improving the signal purity and accuracy of the ranging system.
Model: BP635
Specifications: Customized
Material: Optical glass
NBP635 narrowband filter is an optical filter specially designed to have high transmittance at 635nm wavelength. It has a very narrow transmission band and only allows light near 635nm to pass through, which can effectively isolate other wavelengths of light outside the band. This filter is usually used in applications that require precise wavelength selectivity, such as laser ranging, spectral analysis, imaging systems, etc.

Application fields
- Laser distance measurement and optical sensing
NBP635 narrowband filter is widely used in laser range finders (LiDAR) and optical sensors, especially in laser systems with a wavelength of 635nm. The filter helps to reduce the interference of background light and only allows the target laser echo signal to pass, thereby improving the accuracy and reliability of the system. - Industrial application
In automation, industrial measurement and other fields, NBP635 filter helps to improve the positioning accuracy of laser scanning systems, especially in detection, measurement and positioning tasks with high precision requirements. - Biomedical imaging
In some biomedical imaging systems, lasers with a wavelength of 635nm are often used for tissue imaging and diagnosis. NBP635 filter can help the system filter out-of-band light to obtain clearer imaging results, especially in endoscopy, laser treatment and diagnosis. - Spectral analysis
The 635nm wavelength is also commonly used in spectral analysis. In such analytical equipment, NBP635 filter can help accurately select and analyze the target spectrum, exclude light from other irrelevant bands, and ensure the accuracy of spectral data. - Laser display system
In laser projection and laser display applications, the NBP635 filter helps ensure that the display device only receives the precise laser spectrum, preventing other light sources from affecting the picture quality and ensuring the display effect.
