A common specification error “AG/AR hard coated lens.” This appears regularly on RFQs. It can represent a valid requirement for a combined optical treatment, but in other cases it is used as shorthand without clearly defining the required optical performance. When comparing anti-glare vs anti-reflective cover lenses, it is important to understand that the two treatments solve different optical problems. They operate using different physical principles and produce different vi

Display cover lens coatings can have a significant effect on optical performance, durability and usability. A clear polycarbonate, acrylic or glass substrate may provide the required mechanical properties, but the operating environment often introduces additional requirements such as scratch resistance, glare reduction, electrostatic control, chemical resistance or easier cleaning. Selecting the appropriate coating therefore starts with understanding the application rather th

The Misunderstood ESD Range in Engineering Applications Understanding Surface Resistance Many datasheets state: Surface Resistance: 10⁶ – 10⁹ Ω. But what does this range mean in practical application terms? Surface resistance refers to the rate at which static charge dissipates across a material's surface. Basic Classification of Surface Resistance <10⁵ Ω — Conductive 10⁵ to 10⁹ Ω — Static dissipative >10⁹ Ω — Insulative Cover lenses used over electronics often target th
