Anti-Reflective Infrared: DLC Coatings

At the intersection of advanced technology and cutting-edge design, G&H introduces its Diamond-Like Carbon (DLC) Infrared Anti-Reflective coatings. With optimization for 3-5 µm or 8-12 µm on Silicon or Germanium, our DLC coatings epitomize the company's prowess in confronting and mastering complex coating requirements, delivering exceptional results that transcend the boundaries of conventional optical technology.

G&H's DLC coatings stand at the forefront of high-performance optical applications, offering superior protection and enhanced performance for a wide range of applications. From military systems to sophisticated industrial applications, these coatings can withstand challenging environments, reduce reflection and improve the longevity and effectiveness of the underlying components.

Unwavering in our commitment to quality and precision, G&H's DLC coatings have been engineered to satisfy the stringent military environmental conditions as laid down by MIL-C-48497A, TS1888 Wiper Test, and MIL-STD-810G Method 509.5 (90 days). These military-grade standards testify to our DLC coating's durability, resistance to environmental factors, and ability to endure severe operational conditions.

G&H's DLC coatings are crafted with meticulous attention to detail, leveraging our extensive expertise in advanced coating technologies. These coatings significantly reduce surface reflection across the designated infrared spectrum, enhancing the transmission of critical signals and ensuring clarity of information. The resultant efficiency gains and improved signal accuracy can be pivotal in demanding applications such as infrared sensing, thermal imaging or defense systems.

Designed to perform under rigorous conditions, our DLC coatings are resistant to abrasion, thermal fluctuations, and corrosive environments. This resilience ensures that the underlying optical components remain protected, maintaining their performance over extended periods of use.
