Infrared Aspheric Lens
Infrared Aspheric Lens
Ashley-Tech manufactures high precison aspheric lens, the accuracy can be 0.5-10um. We professionally make complicated optical system, from design, manufacture to assambly. Material range from optical glass to infrared glass with Traditioanl polish and CNC polish. High Precison aspheric lens mainly used for Thermal image.
Upgrade your infrared optical systems with our precision infrared aspheric lenses, designed to reduce spherical aberrations and deliver superior image quality. Ideal for thermal cameras, night vision, IR spectroscopy, and industrial sensing, our lenses are tailored for OEM and commercial applications.
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.
Materials & Optical Performance
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.
