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 AKHAN’s 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 AKHAN’s
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. AKHAN’s 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.”

AKHAN’s 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.
