The NBP8350-270nm Infrared Narrow Band Filter from SENBA is a high-performance optical component designed for precise wavelength selection in advanced infrared sensing and analytical systems. Centered at 8350±50nm with a bandwidth of 270±30nm, it delivers stable and accurate spectral filtering, making it ideal for chemical gas detection, infrared spectroscopy, and scientific measurement applications.
Manufactured using advanced thin-film coating technology on a high-quality silicon substrate, the filter provides high transmittance of ≥75% within the defined passband. It also ensures excellent out-of-band suppression, achieving average transmittance of ≤1% in the 1–7.5µm and 9.3–11µm ranges. This dual-band blocking capability significantly reduces spectral interference, improving signal clarity and measurement accuracy in demanding optical environments.
The silicon substrate offers superior thermal stability, mechanical strength, and long-term reliability, ensuring consistent optical performance in industrial and laboratory applications. With a standard diameter of 100±0.2mm and thickness of 0.5±0.05mm, the filter supports stable integration into a wide range of optical systems. Customization of size, thickness, and substrate is available to meet specific design requirements.
Compared to conventional infrared filters, the NBP8350-270nm provides enhanced spectral selectivity, improved transmission efficiency, and stronger multi-band blocking performance for high-precision infrared applications.
