The NBP3300-160nm Infrared Narrow Band Filter from SENBA is a high-precision optical filtering component designed for selective infrared wavelength transmission in advanced sensing and analytical systems. Centered at 3300±50nm with a narrow bandwidth of 160±30nm, it delivers excellent spectral accuracy for applications requiring precise gas detection, infrared analysis, and spectroscopic measurement.
Manufactured using advanced thin-film coating technology on a durable silicon substrate, the filter provides high transmittance of ≥75% within the target passband. It also ensures strong out-of-band suppression, achieving average transmittance of ≤1% across the 1–11µm range outside the passband. This high rejection ratio significantly improves signal clarity and measurement accuracy in sensitive optical systems.
The silicon substrate offers superior thermal stability, mechanical strength, and long-term reliability, making it suitable for demanding industrial and scientific 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 are available to meet specific design requirements.
Compared to conventional infrared filters, the NBP3300-160nm provides enhanced spectral selectivity, improved transmission efficiency, and superior blocking performance for precision optical applications.
