The NBP7910-160nm Infrared Narrow Band Filter from SENBA is a high-precision optical component engineered for selective wavelength transmission in advanced infrared sensing and analytical systems. Centered at 7910±80nm with a narrow bandwidth of 160±30nm, it delivers excellent spectral accuracy, 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 designated passband. It also ensures ultra-low out-of-band leakage, achieving average transmittance of <0.5% across the 1–11µm range outside the passband. This strong blocking performance significantly reduces spectral interference and enhances signal clarity, resulting in highly accurate and reliable measurement results.
The silicon substrate offers excellent thermal stability, mechanical strength, and long-term durability, ensuring consistent optical performance even in demanding 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 systems. Customization options for size, thickness, and substrate are available to meet specific design requirements.
Compared to conventional infrared filters, the NBP7910-160nm provides superior wavelength selectivity, improved transmission efficiency, and enhanced blocking capability for high-precision infrared applications.
