Product information "LWIR Ge-free Optical Windows"
GH Optics introduces its advanced LWIR Ge-free Optical Windows, a cutting-edge solution designed for long-wave infrared (LWIR) applications in the 8–12 μm spectral range. Engineered using proprietary chalcogenide glass substrates from the GHW series, these windows offer a high-performance alternative to traditional germanium optics. By eliminating the need for germanium, GH Optics delivers a cost-effective, lightweight, and thermally stable solution without compromising on optical quality.
These optical windows are enhanced with either DLC (diamond-like carbon) or HD (hard film) coatings, combined with AR (anti-reflection) layers, achieving transmittance rates exceeding 94%. This makes them ideal for demanding infrared systems where clarity, durability, and cost-efficiency are paramount.
