Frequently Asked Questions
Chalcogenide glass is a family of infrared-transmitting materials composed of one or more chalcogen elements (sulfur, selenium, or tellurium) combined with elements like arsenic or germanium. It offers excellent transmission across the mid-IR and far-IR spectrum and is widely used in thermal imaging, spectroscopy, and remote sensing applications due to its durability, thermal stability, and cost-effectiveness compared to materials like germanium.
Chalcogenide glass coatings enhance optical performance by reducing surface reflection and improving infrared transmission. These coatings are essential for maximizing signal throughput in IR systems, especially in applications like environmental sensing, medical thermography, aerospace targeting, and defense imaging systems.
Andover Corporation is a SCHOTT qualified coating partner, meaning we meet the rigorous standards for applying coatings to SCHOTT’s chalcogenide glass substrates.
Our coatings are applied using optimized low-temperature deposition techniques to protect the integrity of the substrate while delivering consistent, high-performance results across a wide IR spectrum.
Andover’s coatings for chalcogenide substrates support wavelengths from approximately 3 µm to 14 µm, making them ideal for longwave IR (LWIR) applications. Custom coatings can be tailored to specific passbands or broadband ranges, depending on the needs of the system.
