The NBP2700-200nm Infrared Narrow Band Filter from SENBA is a high-precision optical component engineered for selective wavelength transmission in advanced infrared sensing applications. Centered at 2700±50nm with a narrow half bandwidth of 200±30nm, this filter delivers accurate spectral isolation, making it ideal for chemical gas detection, infrared analysis, and spectroscopic measurements.
Manufactured using advanced thin-film coating technology on a silicon substrate, the filter achieves high transmittance of ≥75% within its passband while effectively blocking unwanted wavelengths. It provides excellent cutoff performance with an average transmittance of ≤1% in the 1.5–4µm range outside the passband, ensuring high signal purity and improved measurement accuracy. This precise spectral control enhances system efficiency and minimizes interference in critical detection applications.
The robust silicon substrate ensures excellent thermal stability, mechanical strength, and consistent optical performance. With a standard diameter of 100±0.2mm and thickness of 0.5±0.05mm, the filter supports reliable integration into various optical systems. Customization options for size, thickness, and substrate material are available to meet specific design requirements.
Compared to standard IR filters, the NBP2700-200nm offers superior spectral selectivity, improved transmission efficiency, and high reliability for precision optical applications.
