The NBP9500-450nm Infrared Narrow Band Filter from SENBA is a high-precision optical component designed for selective wavelength transmission in advanced infrared sensing and analytical systems. Centered at 9500±60nm with a relatively wide bandwidth of 450±60nm, it provides stable and accurate spectral filtering, 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 delivers ultra-low out-of-band leakage, achieving average transmittance of <0.5% across the 1–12µm range outside the passband. This strong blocking performance significantly reduces unwanted spectral 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 material are available to meet specific application requirements.
Compared to conventional infrared filters, the NBP9500-450nm provides superior long-wave wavelength selectivity, improved transmission efficiency, and enhanced blocking capability for high-accuracy infrared applications.
