Infrared Optics (IR Optics)
Avantier delivers high-performance infrared optics for advanced applications like thermal imaging, spectroscopy, and high-power lasers. We ensure optimal performance across the infrared spectrum with our custom-crafted components.
Diamond-Turned Precision
We utilize diamond turning machines to achieve sub-nanometer surface finishes and sub-micrometer form accuracies. This allows us to produce precise IR lenses, IR windows, and complex assemblies. Our diamond fly cutting machine also enables intricate diffraction gratings for advanced IR optics design.
Diverse Materials & Coatings
Choosing the right material and coating is essential for IR optics performance. We offer a wide selection of IR substrates and anti-reflection (AR) coatings to maximize transmission and durability.
