Optical Coating Innovations Push Performance

Facebook X LinkedIn Email
The demands of harsh environments and smart glass are challenging optical coatings manufacturers to improve on control, measurement, and cost.

HANK HOGAN, CONTRIBUTING EDITOR, [email protected]

Optical coatings improve the performance of mirrors, lenses, and light-emitting or absorbing semiconductors by enhancing transmission and reducing reflection. They also harden surfaces, allowing components to withstand harsh environments or take pounding from high-power lasers. To continue to meet rising demands, however, coatings need advancements in control, measurements, and cost — areas vendors seek to address by rolling out innovations. A case in point comes from photonic

optical coatings
Optical coatings are thin layers of materials applied to optical components, such as lenses, mirrors, filters, and prisms, to modify their reflective and transmissive properties. These coatings are designed to enhance the performance of optical systems by controlling the way light interacts with the surfaces of the components. The primary purposes of optical coatings include: Antireflection coating: This type of coating is designed to reduce reflections from the surfaces of optical...
