AR Coatings – Custom Designed AR Coatings

Vacuum-Deposited Anti-Reflective Coatings Across the Visible & Near-IR Spectrum

Why Choose Diamond Coatings for Your Custom AR Coating Design

At Diamond Coatings, we specialise in designing and manufacturing high performance anti-reflective (AR) coatings using vacuum deposition techniques, tailored to your spectral, substrate, and durability requirements. Whether in the visible or near-infrared (NIR) range, our coatings deliver superior clarity, transmission, and performance.

Our Capabilities

Wavelength Range & Spectral Flexibility
We can design AR coatings over a broad wavelength range. All our AR Coatings are available in the visible, near-infrared wavelength ranges, including those commonly used for LiDAR applications.
Vacuum-Deposited AR Coatings
Our vacuum deposited AR coatings are custom designed and engineered for your requirements at varying wavelengths to meet your exact requirements. Typical average surface reflectance can be as low as 0.5%.
‘V-Coat’ and Broadband Multilayer AR Options
If your application demands very low reflectance at a single wavelength (or narrow band), our ‘V-Coat’ AR coatings can achieve reflections below 0.1% at that wavelength. For broader spectral ranges (visible, near-IR, IR), our broadband multilayer AR coatings can achieve average reflectance under 0.5% over the band.
Substrates
We work with diverse substrates including optical glass types, sapphire, and a wide range of optical polymers (acrylic, polycarbonate etc.). We coat both glass and plastics.
Incident Angle & Dual/Multiple Band AR Coatings
We can design for specific angles of incidence, dual-band AR coating, or coatings that offer excellent performance over multiple spectral regions.

What Can We Design For You

We offer custom solutions including, but not limited to:

Visible AR coatings for displays, optics, sensors
Near-IR AR for imaging or communication devices
AR + conductive coatings (for e.g. Emi Shielded Windows & Displays)
AR Coatings for all substrate types including plastic, sapphire – optical glasses
Coatings designed for specific incident angles or environmental/durability specs
