    Frequently Asked Questions (FAQ)
    Q: What substrate materials are used for these DLC optical components?
    Our standard DLC (Diamond-Like Carbon) coatings listed in the specification table are applied to Silicon (Si) substrates, which offer excellent transmission properties in the infrared spectrum.
    Q: What sizes are available for the DLC coatings?
    We support sizes ranging from Φ0.1 mm up to Φ300 mm. This wide range ensures compatibility with various micro-optics and large-aperture infrared optical systems.
    Q: What wavelength ranges (HT) do these coatings cover?
    Our coatings cover various ranges in the infrared band, including 2000~14000 nm, 3000-13500 nm, 7000~14000 nm, 7500~13500 nm, and 8000~14000 nm, depending on the specific product configuration.
    Q: What are the average transmission (Tavg) rates for these products?
    Average transmission rates (Tavg) depend on the coating design. For example, DLC single offers ≥50%, DLC+AR configurations offer ≥75%, and AR+DLC configurations reach ≥80% average transmission.
    Q: Can I request custom sizes or specific transmission bands?
    Yes. While the table shows our current stock items, we welcome custom inquiries. Please contact us directly if you require specific dimensions, substrates, or custom coating performance.
