The NBP7300-200nm 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 7300±70nm with a narrow bandwidth of 200±30nm, it delivers accurate spectral filtering performance, making it ideal for chemical gas detection, infrared spectroscopy, and spectrum measurement applications.
Built using advanced thin-film coating technology on a high-quality silicon substrate, the filter ensures high transmittance of ≥75% within the target passband. It also provides excellent out-of-band suppression, achieving average transmittance of <0.5% across the 1–11µm range outside the passband. This strong blocking capability significantly reduces interference, improving signal purity and measurement accuracy in sensitive optical systems.
The silicon substrate offers excellent thermal stability, mechanical strength, and long-term durability, ensuring reliable optical performance in 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 various optical assemblies. Customization options for size, thickness, and substrate material are available to meet specific application requirements.
Compared to conventional infrared filters, the NBP7300-200nm provides superior wavelength selectivity, enhanced transmission efficiency, and improved blocking performance for high-accuracy infrared applications.
