About Infrared Aspheric Lenses
Infrared aspheric lenses are precision optical components optimized for infrared wavelengths. Compared with standard spherical lenses, they enable simplified optical designs, shorter focal lengths, and enhanced imaging performance. Commonly used in thermal imaging, laser systems, night vision, and IR spectrometers, these lenses are essential for high-precision IR applications.
We offer a variety of infrared-grade materials suitable for different wavelength ranges and applications:
· Germanium (Ge): MWIR/LWIR thermal imaging, high transmittance 8–12 μm
· Silicon (Si): Shortwave IR imaging, optical communications
· Zinc Selenide (ZnSe): High-transmission IR, laser optics, 8–12 μm
· CaF₂ / Chalcogenide: Broadband IR applications with low absorption
All lenses are available with anti-reflection coatings for enhanced performance across target IR wavelengths.
