Kopp Borosilicate Glass vs. Thermoplastics
Wherever lighting must endure harsh environments or be exposed to the elements, cover glass lenses and optics must have abrasion resistant properties in order to maintain efficiency and ensure safety. In the aerospace lighting industry, SAE is working on a regulation that would require exterior lighting designs to account for abrasion. Being aware of the abrasion resistance properties allows engineers to design optimized lighting products and allows end users to make informed purchasing decisions based on the total cost of ownership.
The abrasion video above documents both Taber Abrasion and falling sand tests performed on borosilicate glass and two types of thermoplastics, including a hard-coated polycarbonate and acrylic lens.
