    Frequently Asked Questions (FAQ)
    Q What are the key benefits of DLC (Diamond-Like Carbon) coatings on Silicon substrates?
    DLC coatings offer extreme surface hardness, excellent wear resistance, and chemical durability. When applied to Silicon (Si) substrates, they protect the optics from harsh environmental conditions while maintaining high transmission in the infrared (IR) spectrum.
    Q Can I request custom sizes outside the standard Φ0.1~300 mm range?
    Yes. While our standard stock sizes range from Φ0.1 mm to Φ300 mm, we specialize in custom optical fabrication. Please contact us with your specific dimensions and tolerance requirements.
    Q What does "Tavg ≥ 75%" indicate in the product specifications?
    Tavg refers to the Average Transmission percentage within the specified operating wavelength range (HT nm). A value of ≥75% ensures high optical efficiency and throughput for your infrared imaging or sensing systems.
    Q What is the difference between DLC single and DLC Dual coatings?
    DLC single refers to a Diamond-Like Carbon coating applied to one surface of the substrate (often combined with an Anti-Reflection coating on the other side), while DLC Dual refers to DLC coatings applied to both optical surfaces for maximum environmental protection.
    Q How can I obtain the detailed spectrogram data for a specific product?
    You can click on the spectrogram preview images in the table to view the full-size measurement charts. For high-resolution files or specific batch test reports, please reach out to our support team.
