Thin Layers, Big Impact: I-Photonics Innovations in BBAR Coatings
In this edition, we highlight broadband anti-reflection (BBAR) coatings engineered for the critical 8–14 µm LWIR range. By minimizing surface reflections on ZnS and Ge optics, these multilayer coatings achieve transmission levels above 94–98%, unlocking higher sensitivity and performance in thermal imaging, laser systems, and IR sensors.
