Target Applications
Due to its specialized meniscus profile, this lens delivers tighter spot sizes and improved wavefront integrity in mid-to-far infrared optical systems. It is ideally suited for CO2 mid-infrared laser beam steering, industrial laser cutting alignment, thermal target collimation, and custom spectral analysis. Its minimal bulk absorption makes it a key element in advanced beam control optics and protective system assemblies alongside heavy-duty IR windows.
Customization & Engineering Support
To support flexible research and system integration, iroptical maintains vast off-the-shelf inventory alongside fully customizable fabrication options. We provide specialized anti-reflective (AR) coating configurations (such as 10.6 µm BBAR), non-standard edge mounting modifications, and custom diameter resizing. Every lens undergoes full spectral and dimensional validation to ensure seamless deployment and fast delivery schedules.
