Applicable to infrared imaging, monitoring, infrared inspection, telemetry, and infrared spectroscopic optical systems.
As a classification of Germanium window, these products not only improve the light transmittance of Germanium windows, but also enhance their durability and resistance to environmental influences.
Crafted from high-purity germanium, this window excels in IR transparency and is ideal for thermal imaging and IR spectroscopy. Each window is customized to your specifications and available with AR/AR (anti-reflective) or AR/DLC (diamond-like carbon) coatings. These coatings enhance durability, minimize reflection, and improve transmission efficiency. Perfect for demanding environments, our germanium windows offer exceptional performance and reliability. Trust our expertise to provide tailored infrared optical solutions that meet the highest industry standards.
