A:
AR anti-reflective coating is a multi-layer thin film plated on the surface of optical components via vacuum coating equipment. Its core working principle is to offset reflected light through light wave interference effect, so as to greatly reduce surface light reflection loss:
- For surveillance camera domes and imaging lenses: Eliminate glare under strong sunlight and restore true, distortion-free monitoring image;
- For laser transmission optical windows and prisms: Reduce laser energy reflection loss, improve laser transmission accuracy and avoid stray light interference inside the optical path; It is the most widely used standard coating for almost all visible and near-infrared optical equipment.
