The NBP9650-240nm Infrared Narrow Band Filter from SENBA is a high-performance optical component engineered for precise wavelength selection in advanced infrared sensing and analytical systems. Centered at 9650±50nm with a bandwidth of 240±30nm, it delivers reliable spectral filtering performance, 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 stable transmittance of >70% within the defined passband. It also provides strong out-of-band suppression, achieving average transmittance of <1% across the 1–11µm range outside the passband. This excellent blocking capability significantly reduces spectral noise and interference, improving signal clarity and measurement accuracy in demanding optical environments.
The silicon substrate offers excellent thermal stability, mechanical strength, and long-term reliability, ensuring consistent optical performance in both 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 options for size, thickness, and substrate are available to meet specific application requirements.
Compared to conventional infrared filters, the NBP9650-240nm provides improved wavelength selectivity, reliable transmission efficiency, and enhanced blocking performance for high-precision infrared applications.
