New Webinar: Lens Material Selection for Exterior Aircraft Lighting

New Webinar: Lens Material Selection for Exterior Aircraft Lighting

When designing an exterior aircraft lighting fixture, it is necessary to choose a cover lens material that is resistant to pressure, abrasion, and impact.  With the onset of LED technology, manufacturers of lighting fixtures essentially have two options for cover lens materials: glass or plastic. This decision affects safety, maintenance, and total cost of ownership.…

Mechanical Properties of Glass: Design to Survive Stress, Impact, and Abrasion

Mechanical Properties of Glass

When designing a lens for a harsh environment, you need to choose a material that is resistant to pressure, abrasion, and impact. Some applications, such as exterior aircraft lighting, can push a material to its limits. Exterior aircraft lenses are exposed to smog, dust, and other air pollutants at very high speeds; the resulting impacts…
