Webinar: Overcoming DLC Coating Challenges on Chalcogenides

Live Event: Wednesday, February 24, 2021 – 1:00pm – 2:00pm ET

Over the past decade, we’ve seen chalcogenide glass substrates become a preferred choice for IR optics. They offer many advantages that legacy materials such as germanium, silicon, and others simply cannot match. Because chalcogenide glasses are softer and prone to scratches, a protective layer is critical. A diamond-like carbon (DLC) coating is ideal for its extreme durability to withstand the harshest environmental conditions. However, coating chalcogenides with DLC is a notoriously challenging endeavor plagued by adhesion problems and coating defects.

In our “Overcoming DLC Coating Challenges on Chalcogenides” webinar, we will compare chalcogenides’ properties to more traditional substrates to understand their growing popularity and delve into the adhesion challenges they present throughout the coating process. We will share how EMF has successfully produced dependable, long-lasting DLC coatings on chalcogenides at scale, along with our top tips to ensure your coating partner has the capabilities and capacity to deliver the precision coating solutions you need. And finally, we’ll wrap up with a Q&A session so you can confidently obtain the best optics for your IR applications.
