Anti-Reflection (AR) Coating Services for Optical Windows
In precision optical systems, surface reflection is a major cause of energy loss, ghost images, and degraded system performance. At YOUJIA OPTICAL, we offer high-performance Anti-Reflection (AR) Coating services tailored for various optical windows. Utilizing advanced Ion-Assisted Deposition (IAD) technology, our thin-film coatings maximize transmission from Ultraviolet (UV), Visible (VIS), to Near-Infrared (NIR) wavelengths.
Substrates and Spectral Ranges
We apply custom AR coatings to a wide variety of precision optical substrates, ensuring optimal adhesion and spectral performance:
| Substrate Material | Wavelength Range | Uncoated R (Single Surface) | Coated Performance |
|---|---|---|---|
| JGS1 Fused Silica | 200 – 2100 nm (UV-NIR) | ~ 3.5% | R < 0.2% (V-coat) / R < 0.5% (BBAR) |
| H-K9L (N-BK7) | 350 – 2000 nm (VIS-NIR) | ~ 4.2% | R_avg < 0.25% (400-700nm) |
| Sapphire | 180 – 4500 nm (UV-MWIR) | ~ 7.7% | R < 0.5% (Custom Multilayer) |
Our Coating Options
- Single-Layer MgF2 Coating: The most cost-effective solution with high durability. Ideal for high-index substrates like Sapphire, reducing reflection across a broad band.
- V-Coat Anti-Reflection (V-AR): Optimized for maximum transmission at a single specific wavelength (e.g., 355nm, 532nm, 1064nm). Perfect for high-power laser protection windows.
- Broadband Anti-Reflection (BBAR): Engineered to minimize reflection over a wide spectral range (e.g., 400-700nm or 700-1100nm). Widely used in industrial imaging and spectroscopic systems.
Quality Assurance and Specifications
Every coating batch at YOUJIA OPTICAL undergoes stringent testing to meet demanding industrial and military standards (MIL-SPEC).
- Angle of Incidence (AOI): Designed for 0° (Normal Incidence) as standard, or customized up to 45° upon request.
- Laser Induced Damage Threshold (LIDT): High damage resistance for laser windows using durable dielectric oxide materials ($SiO_2$, $HfO_2$, $Ta_2O_5$).
- Durability Tests: Excellent adhesion (3M tape test), moderate abrasion resistance, and environmental stability under high humidity/temperature conditions.
