The 8–14µm Infrared Narrow Band Filter from SENBA is a high-precision optical component designed for selective transmission within the long-wave infrared (LWIR) spectrum. Utilizing advanced thin-film coating technology on a silicon substrate, this filter ensures accurate spectral performance for demanding infrared sensing and imaging applications.
Engineered to deliver high transmittance of over 75% within the 8–14µm range, it is ideal for thermal imaging, thermopile sensors, and environmental monitoring systems. The filter provides excellent blocking characteristics, achieving less than 1% average transmittance in the 1–7µm range, effectively eliminating unwanted shorter wavelength interference. This results in improved signal clarity, enhanced measurement accuracy, and superior system efficiency.
The silicon substrate offers excellent thermal stability, mechanical durability, and consistent optical performance under varying environmental conditions. With a standard diameter of 150±0.50mm and thickness of 0.62±0.05mm, the filter is suitable for a wide range of optical system integrations. Customization options for size, thickness, and substrate material are available to meet specific application requirements.
Compared to standard IR filters, this narrow band filter provides enhanced spectral selectivity, improved transmission efficiency, and reliable long-term performance.
