The NBP5300-180nm Infrared Narrow Band Filter from SENBA is a high-precision optical component engineered for selective infrared wavelength transmission in advanced gas sensing and spectroscopic systems. Centered at 5300±50nm with a narrow bandwidth of 180±30nm, it delivers excellent spectral accuracy, making it ideal for chemical gas detection, infrared analysis, and scientific measurement applications.
Fabricated using advanced thin-film coating technology on a high-quality silicon substrate, the filter provides high transmittance of ≥75% within the defined 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 superior blocking performance significantly reduces interference and enhances signal purity, resulting in highly accurate measurement results.
The silicon substrate offers excellent thermal stability, mechanical strength, and long-term durability, ensuring reliable optical performance in demanding 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 application requirements.
Compared to conventional IR filters, the NBP5300-180nm provides enhanced spectral selectivity, improved transmission efficiency, and superior blocking performance for high-accuracy infrared applications.
