Choosing the right cover lens material can have a significant impact on optical performance, durability and appearance. Our material evaluation frames allow engineers to compare polycarbonate, acrylic and glass substrates and specialist surface treatments before making a material selection.

The wrong starting question “Should we use glass or plastic?” This is not a material preference decision. It is a performance risk decision. Both polymer and glass can deliver excellent cover lens performance. Both can fail badly when misapplied. The correct question is: What environment, validation standard, and mechanical stress will the lens experience? Mechanical Performance Glass Strengths: Excellent scratch resistance High surface hardness Stable optical clarity over ti
