    ❓ Frequently Asked Questions (FAQ)
    Q1: What substrate materials are available for these bandpass filters?

    We offer various substrate options tailored to specific wavelength applications, including Sapphire, Silicon (Si), Germanium (Ge), Zinc Selenide (ZnSe), Quartz, Glass Ceramic, and D263T glass.

    Q2: Can I order custom sizes for the filters?

    Yes, our standard manufacturing size ranges from Φ0.1 mm up to Φ300 mm. We can accommodate custom dimensions, shapes, and thicknesses based on your specific requirements.

    Q3: What does the "50% Cut on Left" and "50% Cut on Right" represent?

    These values indicate the specific transition wavelengths where the transmission level drops to 50% of the peak transmission, defining the start and end boundaries of the passband region.

    Q4: How is the out-of-band blocking performance of these filters?

    Our filters feature deep blocking capabilities, with an average transmission (Tavg) of less than 1% (or less than 10% on select models) across specified blocking ranges from 200 nm up to 20,000 nm.

    Q5: What is the average transmission (Tavg) in the high-transparency area?

    Depending on the specific filter model and substrate material, our bandpass filters achieve high transmission rates of Tavg ≥ 75%, ≥ 80%, ≥ 85%, or ≥ 90% in their designated passband regions.

    Q6: How can I obtain a detailed spectrogram for a specific filter?

    You can view the spectrogram preview directly in the table. For high-resolution files or customized testing curves, please contact our support team via the inquiry form.
