Coating Polymer Optics: Perfecting the Science

This article is brought to you by: 

Advances in optical polymers coupled with developments in fabrication methods have led to more optics designers choosing polymer components over glass and metal optical parts – and its no surprise why. Lower cost, faster production, and less weight are just a few of the myriad advantages that polymer-coated optics lend manufacturers. 

The Solution to Coating DLC on Chalcogenides

This article is brought to you by: 

Chalcogenides offer many advantages that legacy IR materials simply cannot match, but they do require a diamond-like carbon (DLC) coating so the optic can withstand the harshest environmental conditions. However, coating chalcogenides with DLC has been notoriously challenging and plagued by adhesion problems and coating defects.  Until now.
