AKHAN Semiconductor, a technology company specializing in the fabrication and application of lab-grown, electronics-grade diamond, announced today the issuance by the United States Patent and Trademark Office (USPTO) of a patent covering AKHANs next generation diamond based multilayer antireflective coating systems, key in military & aerospace sensor and detector applications, amongst others.

The granted and issued patent, 10,254,445, is a key addition to AKHANs breakthrough Miraj Diamond Glass intellectual property portfolio, and enables new capabilities in optical sensing, detecting, and transmission. Through integration of high-quality diamond multilayer materials, the novel system allows for optical components with ultra-hardness, scratch-resistance, high thermal conductivity, hydrophobicity, chemical and biological inertness, and with high transmittance at a variety of critical angles.

Due to diamond’s absorption spectra in the medium wavelength infrared region, the material has been historically absent for infrared application use. However, through our novel diamond-based multilayer materials, it is now possible to capture the favorable properties of diamond for more rugged systems use, such as experienced in battlefield conditions, explains AKHAN Founder & CEO, Adam Khan.

Previous antireflective coatings have suffered from delamination, degradation, and fluctuating optical transmissivity. AKHANs Miraj Diamond materials provide high transmissivity infrared windows with high reliability, said AKHAN Chief Technology Officer Bill Alberth. We look forward to announcing new products featuring this patented technology soon.

AKHANs flagship Miraj Diamond Glass for consumer display is 6x stronger, 10x harder, and runs over 800x cooler than leading glass competitors like Gorilla Glass by coating standard commercial glass such as aluminosilicate, BK7, and Fused Silica with proprietary lab-grown nanocrystalline diamond. Diamond-based technology is capable of increasing power density as well as creating faster, lighter, and simpler devices for consumer use.
