Anti-Reflection (AR) Coatings
Anti-reflection coatings are essential optical enhancements used in everything from everyday eyewear to high-precision scientific instruments such as telescopes, microscopes, and cameras.
When light hits an optical surface, some of it is reflected, some transmitted, and some absorbed. Reflected light reduces the efficiency of optical systems and introduces glare—an issue that can degrade image quality, particularly in imaging devices. AR coatings reduce reflectance by using destructive interference. The refractive index of the coating is carefully selected to fall between that of air and the substrate (e.g., glass). Reflections from the top and bottom interfaces cancel each other out, allowing more light to pass through.
AR coatings are a cost-effective way to boost optical performance. With over 20 years of experience, Intlvac has refined its coating processes using in-house technology to deliver some of the industry’s most reliable and advanced coatings.
We offer anti-reflection coatings for a wide range of substrates and wavelengths, including the visible (VIS), near-infrared (NIR), short-wave infrared (SWIR), and mid-wave infrared (MWIR) spectral regions. All coatings are non-radioactive and meet stringent durability standards.
Available Coating Types
1. Narrowband AR (V-Coating)
Description:
Designed for a single wavelength or very narrow band applications—commonly used in laser receivers. Compatible with most optical materials. The sample spectrum shown features a flat window coated using our reactive magnetron sputtering process with plasma assist (PARMS).
Durability Standards:
2. Broadband AR
Description:
Engineered for broad spectral coverage, including visible light. Can be applied to a variety of substrates such as BK7, BK10, fused silica, quartz, SK2, SF4, and more.
Durability Standards:
3. MgF₂ AR Coating
Details available upon request.
4. Dual-Band AR Coating
Supports systems requiring optimized transmission in two distinct wavelength ranges.
