    Frequently Asked Questions

    • What substrate material is used in this bandpass filter? +
      This bandpass filter uses a Silicon (Si) substrate, which offers excellent transmittance in the near-infrared range and provides superior mechanical and thermal stability for demanding optical applications.
    • What is the high-transmittance (HT) wavelength range of this filter? +
      The high-transmittance (HT) area of this filter covers 4550 to 5050 nm. Within this passband, the transmittance (Tp) is guaranteed to be ≥90%, ensuring highly efficient signal throughput.
    • What is the blocking range of this bandpass filter? +
      The filter provides effective blocking from 1000 nm to 11000 nm (outside the passband). This wide blocking range makes it ideal for applications that require strong out-of-band rejection across both near-infrared and mid-infrared regions.
    • What are the typical applications for this type of mid-infrared bandpass filter? +
      Mid-infrared bandpass filters with this specification are commonly used in gas sensing and analysis, laser systems, environmental monitoring, medical diagnostics, thermal imaging, and scientific spectroscopy where precise wavelength selection is critical.
    • Can this filter be customized for different wavelength ranges or substrates? +
      Yes, customization is available for different center wavelengths, bandwidths, substrate materials, and coating specifications to meet specific project requirements. Please contact our technical team to discuss your custom optical filter needs.
    • How should this bandpass filter be stored and handled? +
      The filter should be stored in a clean, dry environment away from moisture, dust, and direct sunlight. Handle only by the edges using clean gloves or lens tissue. Avoid touching the coated optical surfaces to prevent contamination or damage that could affect transmittance performance.
