What anti-reflective (AR) coating services do you offer for optical glass?

Update Time:2026/4/28
At Felix Glass, we offer a comprehensive range of anti-reflective (AR) coating services for BK7 and K9 optical glass parts, tailored to meet the specific wavelength and performance requirements of your applications.

Our AR coating services include both single-layer and multi-layer coatings for different spectrums, including visible light (VIS), near-infrared (NIR), and ultraviolet (UV). Single-layer AR coatings are designed for basic applications, providing a moderate reduction in surface reflection and a corresponding increase in light transmittance. Multi-layer AR coatings, on the other hand, are engineered for high-performance applications, offering significantly lower reflectivity and higher transmittance across a broader wavelength range.

Our coating process is carried out in a clean room environment using advanced vacuum deposition equipment, ensuring consistent coating quality and uniformity across the entire surface of the optical glass parts. Before coating, all parts undergo a thorough cleaning process to remove contaminants and ensure optimal coating adhesion. After coating, each part is inspected for coating thickness, uniformity, and adhesion to ensure they meet our quality standards.

The benefits of AR coating include increased light transmittance, reduced glare and reflection, improved contrast, and enhanced scratch resistance. For example, a multi-layer AR coating can increase the visible light transmittance of BK7 glass from around 91% to over 98%, making it ideal for applications such as camera lenses, microscope objectives, and optical windows.

We can customize the AR coating specifications to match your exact requirements, including the target wavelength range, minimum transmittance, and maximum reflectance. Whether you need a standard coating for a common application or a custom coating for a specialized project, we can provide you with a solution that meets your needs.

Our experienced engineering team will work with you to understand your application requirements and recommend the most suitable AR coating for your optical glass parts. We also provide coating test reports to verify the performance of the coated parts, giving you confidence in their quality and reliability.

If you have any questions about our AR coating services or need help selecting the right coating for your project, please contact our sales team today.
