The NBP8550-210nm Infrared Narrow Band Filter from SENBA is a high-precision optical filtering component designed for selective wavelength transmission in advanced infrared sensing and analytical systems. Centered at 8550±50nm with a narrow bandwidth of 210±30nm, it delivers excellent spectral accuracy, making it ideal for chemical gas detection, infrared spectroscopy, and spectrum measurement applications.
Manufactured using advanced thin-film coating technology on a high-quality silicon substrate, the filter ensures high transmittance of ≥75% within the designated passband. It also provides strong out-of-band suppression, achieving average transmittance of ≤1% in the 1–7.8µm and 9.5–11µm ranges. This dual-region blocking capability significantly reduces spectral interference, improving signal clarity and measurement precision in demanding optical systems.
The silicon substrate offers excellent thermal stability, mechanical strength, and long-term reliability, ensuring consistent optical performance in industrial and laboratory environments. 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 assemblies. Customization options for size, thickness, and substrate material are available to meet specific application requirements.
Compared to conventional infrared filters, the NBP8550-210nm provides superior wavelength selectivity, improved transmission efficiency, and enhanced multi-band blocking performance for high-accuracy infrared applications.
