In this edition, we explain why ZnS, ZnSe and chalcogenide glasses each need their own DLC process, and how hybrid AR + DLC coatings on the DIAMANTA ion-beam PECVD system protect IR optics in harsh environments.

Narrowband optical filters isolate a precisely defined wavelength band from a much broader optical background, delivering higher signal-to-noise ratios and selective detection of weak optical signals. In this edition we show how I-Photonics engineers complex PARMS interference coatings — over one hundred dielectric layers — and demonstrate an astronomy-grade [S II] narrowband filter near 673.1 nm with 93.89% peak transmission and a ~3.1 nm FWHM.

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