When Every ppm Matters: The Science Behind Low Absorption Optical Coatings

At the frontier of high-power lasers and gravitational wave detection, optical losses are now measured in ppm. We explore how electric field engineering and thermal relaxation push IBS thin films into the single-digit ppm absorption regime, enabling HR mirrors with reflectance up to 99.9966%.

How Precision Optical Mirrors Increased LiDAR Detection Range by 2 km

How precision optics boosts 1550 nm LiDAR range and signal fidelity — a real 13% system improvement case study.

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.
